It turns out that the Israeli democracy is far more mature. The US democracy is a petulant child.
From Glenn Greenwald:
All of this underscores a fundamental difference between Israel and the right-wing faction in the U.S. For Israel -- whatever else you might think about its policies and government -- war is an extremely serious matter. They don't send other people's children off to fight the wars they cheer on; their own children fight the wars. During the invasion of Lebanon, missiles continuously landed deep in Israeli territory, killing killing or wounding hundreds and forcing hundreds of thousands to flee their homes or live in bomb shelters.
Unlike our chest-beating, play-acting warriors here, war is not something that Israelis cheer on for fun like a video game from behind their computer monitor or sitting on their sofa watching CNN or Fox. When they advocate wars, they pay a price. As a result, they don't have the luxury of shutting their eyes and pretending that things are going well -- or exploiting accusations of treason in order to stifle war criticisms -- or cheering on failing wars for years for no reason other than to avoid having to admit error or feel weak.
All of that stands in such stark contrast to the shrinking though still-substantial faction in this country who see war as a fun and sterile video game that never requires them to pay any price -- no matter how profoundly the war fails. That is what enables them to cheer on those wars for years without end, to urge still new and more destructive ones, and to childishly insist that there is something noble and compulsory about keeping quiet, loyally cheering on the Leader's war, and pretending that things are going great and we are on the verge of success.
