On Friday night, after prayers, a mob of several thousand Egyptians attacked the Israeli embassy in Cairo.

Previously, the Egyptian authorities had raised a defensive wall around the embassy but that seems to have acted like a red rag to a bull.

A determined mob broke down the wall and entered the compound, torching it and burning the Israeli flag for the second time in a month.

Some reports suggested that this group was Islamist, others that it was Communists trying to destabilise the country.

What is clear is that several thousand turned up to break in to the compound. More than a thousand were injured and 3 actually died, which is insane.

Meanwhile, the Egyptian police stood back and did nothing. As the mob hammered at the walls and door where the remaining few embassy staff members were huddled, the members of staff of the Israeli embassy were in contact with Prime Minister Netanyahu and asked him to convey their final messages to their loved ones. They were clearly in fear of their life.

According to some reports President Obama called the Egyptian government and demanded they honour their obligations under international law.

Some say Obama even threatened the Egyptians with dire consequences if they did not act to save the embassy staff.

Soon after, commandos rescued the remaining Israelis and smuggled them out of the embassy wearing Arab attire.

Avi Mayer (@avimayer) has reported via Twitter from several sources. Here are some snippets:

I don’t get it. When Netanyahu/Barak called, Tantawi was unavailable. When Obama/Panetta called, he picked up. Is he screening our calls?

Walla: Fearing #Cairo protesters would pretend to be rescuers, #Egypt commandos used “secret sign” and #Israel emb guards opened door.

When I tweeted about the incident earleir this evening a received a couple of brusque rejoinders including this one which I answered vias a retweet:

RT @fat_lam: @RayPCook at least no Israeli was killed, #israel on other hand did kill innocents<<what do you think would have happened to the #Israelis if they had not been saved by #Egyptian army?

This links in to the presumed spark to this incident. Over a week ago now 8 Israelis were killed in separate incidents near Eilat on the border with Egypt when terrorists fired automatic weapons and artillery rounds at a car, a bus and IDF soldiers.

As the IDF pursued the perpetrators and despite every effort not to hit anyone on the Egyptian side, several Egyptian soldiers were killed by Israeli fire. One of the reasons given is that the terrorists were actually dressed in Egyptian uniforms or something similar.

The tweeter above is not concerned with Israeli deaths just the Egyptian ones despite an expression of regret from Israel.

This is the cover story for the Egyptian mob.

The truth is that no excuse is required for a mob raised on an anti-Semitic diet of Jew-hatred.

Egyptian clerics are often very keen to demonise Israel and the Jews.

Mein Kampf and The Protocols of the Elders of Zion appear to be standard reading and are freely available.

Israel is blamed for every calamity in a press which is often hysterically (in both senses) obsessed with Israel hatred: when a tourist was attacked and killed by a shark in Sharm-el-Sheikh, Mossad were blamed;

an Israeli is currently under arrest for spying even though there does not appear to be a case to answer;

during the demonstrations in Tahrir Square foreign journalists were accused of being Israeli spies and the CBS reporter Lara Logan was brutally sexually assaulted and accused of being an Israeli in February.

Even yesterday the appearance of a female journalist was met with accusations that she was Israeli and she had to be rapidly whisked away.

So it appears that the Arab Spring has become an excuse for mob rule and taking the law into ones own hands in certain sections of Egyptian society.

These same people who accuse Israel of breaking international law are only too quick to do the same themselves.

There are some positives:

The Egyptian authorities have arrested and arraigned several of the trouble-makers

A Bahraini government spokesman tweeted:

Not protecting the Israeli embassy in Cairo is a clear violation of the Vienna Convention of 1961 on diplomatic relations

I’m not completely au fait with the relations between Bahrain and Israel, but given the almost uniform hatred of the Arab world against Israel, this is a very decent thing to have said, and it constitutes a reprimand.

But here’s the ‘whatif’ bit. The guards inside the embassy had guns. They even fired some warning shots in the air according to Avi Mayer (@avimayer). They were given permission to open fire on the crowd should their lives be in danger.

Now here’s the thing; imagine that – they asked permission to save their own lives knowing that if it came to this the diplomatic fallout would inevitably go against Israel.

So, what if the commandos were a little late and the mob had battered down a wall and there were the guards, guns drawn, and the mob attacked them, presumably filled with jihadi zeal and the prospect of paradise for dying whilst trying to kill some Jews.

Does this sound familiar? Think Mavi Marmara, a somewhat different arena, yet, nevertheless, armed Israelis with no intention of lethal conflict are faced with a baying mob ready to lynch them.

So what if the Israelis fired, killed nine or ten of their attackers and then the Egyptian cavalry arrived and saved them.

What would the world have said? Would they be condemned for using excessive force as the Palmer report found?

With more Egyptian blood on their hands would Israel have been blamed for its citizens defending what is, in international law, sovereign territory?

What would all the leftists say? What would the Guardian say? I can take a pretty good guess; they would have found a way to condemn the Israelis. They would quote members of the mob saying that they had no intention of hurting anyone.

Some elements in Israel would call for an end to the peace treaty. The UN would have demanded an investigation.

Yet, the situation is not dissimilar to the Mavi Marmara. If a mob is coming at you with clearly lethal intent, what is a proportionate response?

And, ‘what if’ the Egyptian commandos got there too late and six Israelis were lynched? General rejoicing across the Arab and Muslim world whilst their governments would disingenuously condemn the deaths and, at the same time, try to ‘explain’ them in the ‘context’ of the ‘incident’ near Eilat.

Israelis would demonstrate outside the Egyptian embassy – maybe. But as now, and as always, Israelis would respect the Egyptian embassy physically.

It should be noted that before the mob attacked the Israeli embassy in Cairo, a man was arrested in Tel Aviv for throwing a stone at the Egyptian embassy. Throwing a stone. One man. So much for the evil, murderous Israelis so often characterised across the world.

If the Israelis had killed anyone we would have a third incident, along with the Flotilla and the terrorist attack on the highway near Eilat where Israelis killed those trying to kill them and were condemned for doing so.

With a poll showing the majority of Egyptians wanting to end the 32 year treaty with Israel, despite the commendable, but somewhat belated actions of the Egyptian government, it is clear that when a new government is elected it is not beyond the bounds of possibility that it will do so on an anti-Israel ticket.

Additionally, 60%, according to another poll, want to restore Sharia Law.

The prospects for a continued peace with Israel look fragile and would only be maintained for strategic reasons rather than a wish for peace.
