"It's Disproportionate. . ."
means...
"we don't want you to win."
Disproportionate is the sly way of saying it's excessive.
When a nation implements military force, it exherts enough force to get the enemy to capitulate and or comply with it's wishes. The enemies of Israel have not capitulated or complied with it's demands. Therefore Israel has not used excessive force. It has used a level of force that has not achieved Israel's goals. If anything, it has used too little force.
Disproportionate? Excessive? Bull s--t!
No, "disproportionate" means "not enough Jews are dying."
What is "disproportionate" is the whining of the gasbags at the Washington Post. If only a missle were pointed their way!
