If the “left” favored Taiwan and Ukraine, they would be demanding expanding the military to Cold War levels (at least), and reducing domestic spending while raising taxes to pay for it. The same holds true of the “right”. This suggests that the current political leadership is not very serious about supporting Israel, Ukraine or Taiwan, and that the Hamas outrage is calling the American “bluff”.
Coffee addct: Those who supported the Nazis for an ulterior motive but did not support the Holocaust are NOT seen in the same light as the Nazis. This includes Finland (allied with Germany against the Soviet Union, but only as a co-belligerent and never at war with the other Allies, and refused to persecute Jews or even to exclude them from its army) and Japan (allied with Germany but refused German requests to round up and execute Jews within its territories).
