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.
