You're right. You don't get it.
Convenient of you to forget the US acquired the Southwest, California, Florida, by conquest, then by treaty.
Modern Israel was founded by socialists, runs communes, has high taxes, nationalized healthcare, and a bossy government. The US paid Mexico to settle their claims, like Israel should do if they want legal title. Israel is the only instance I know of where conservatives support the territorial expansion by force by a socialist state and blather on emotionally without regard to the rule of law. It would be cheaper for Israel, and the U.S. taxpayer, if they expanded vertically instead of horizontally. It’s as if they like to fight the Arabs for its entertainment value.
