This policy has more to do with the leadership. Not the people. The voters in general don’t seem to care much about anything today, whether it’s Israel, Russia, debt, failed entitlements, etc. enough voters are driving their decisions about unimportant issues or cult of personality.
If a president backed Israel in this, it would be accepted too. No one seems to give a damn either way on big issues.
The American people spoke up against Obama’s stupid proposed Syrian adventure. After a decade of war, the American public are slowly awakening to the political elite’s addiction to endless global conflict.
