The whole idea that Israel's response to Hezbollah's rocket attacks has been "disproportionate" is plainly ludicrous and can only be believed or proclaimed by someone with either no concept of morality or no understanding of history. This plain on the face. There's little hope for those who denounce Israel because of their own amorality, but for those who need instruction in the history of war I suggest you go read Charles Krauthammer's explanation of how Israel's moral scrupulousness is being paid in blood.
The word that obviates all thinking and magically inverts victim into aggressor is "disproportionate," as in the universally decried "disproportionate Israeli response."
When the United States was attacked at Pearl Harbor, it did not respond with a parallel "proportionate" attack on a Japanese naval base. It launched a four-year campaign that killed millions of Japanese, reduced Tokyo, Hiroshima and Nagasaki to a cinder, and turned the Japanese home islands to rubble and ruin. Disproportionate? No. When one is wantonly attacked by an aggressor, one has every right — legal and moral — to carry the fight until the aggressor is disarmed and so disabled that it cannot threaten one's security again. That's what it took with Japan.
Britain was never invaded by Germany in World War II. Did it respond to the blitz and V-1 and V-2 rockets with "proportionate" aerial bombardment of Germany? Of course not. Churchill orchestrated the greatest land invasion in history that flattened and utterly destroyed Germany, killing untold innocent German women and children in the process.
The perversity of today's international outcry lies in the fact that there is indeed a disproportion in this war, a radical moral asymmetry between Hezbollah and Israel: Hezbollah is deliberately trying to create civilian casualties on both sides while Israel is deliberately trying to minimize civilian casualties, also on both sides.
Read the whole thing, learn a little, and hopefully adjust the calibration on your moral compass if necessary.
