But the Syrians themselves have officially confirmed that military installations were hit by the Israelis. And not for the first time during the rebellion. The Fateh-110 – the new version, at least – has a range of perhaps 250km. And it could indeed reach Tel Aviv from southern Lebanon. If the Hezbollah has actually acquired any. But why would the Syrians send them, as US sources were also claiming last night, when the Americans themselves claimed only last December that the Syrians had used the same ground-to-ground missiles against rebel forces in Syria.

In other words, the Syrian regime was prepared to dispense with their rockets to Lebanon when they were already using them in the brutal war in Syria… Now there are other questions to be asked. If the Syrian air force can use their MiGs so devastatingly – and at such civilian cost – against their enemies inside Syria, why couldn’t they have sent their jets to protect Damascus and attack the Israeli aircraft? Isn’t the Syrian air force supposed to be guarding Syria from Israel? Or are the MiGs just not technically able to take on Israel’s state-of-the-art (American) hardware? Or would that just be a step too far?

Much more important, however, is the salient fact that Israel has now intervened in the Syrian war. It may say it was only aiming at weapons destined for the Hezbollah – but these were weapons also being used against rebel forces in Syria. By diminishing the regime’s supply of these weapons, it is therefore helping the rebels overthrow Bashar al-Assad. And since Israel regards itself as a Western nation – best friend and best US military ally in the Middle East, etc, etc – this means that “we” are now involved in the war, directly and from the air.

Let’s see if the US and the EU condemn Israel’s air attacks. I doubt it. Which would mean, if we are silent, that we approve of them. Silence, to quote Sir Thomas More, gives consent.

So now the Iranians and Hizballah are accused of intervening in Syria – true, though not to quite extent we are led to believe – and Qatar and Saudi Arabia funnel weapons to the rebels – true, but not quite enough weapons, as the Syrian rebels will tell you – and the Israelis have joined in. We are now militarily involved.
