1. It is a mistake to see Eretz Yisrael as a unique case. If the United States is opposed to the “axis” that include China, Russia, Iran, and North Korea – the United States will help Israel. If the United States returns to the “America First” foreign policy of the pre-WWII era, it will at most offer Israel moral support but to avoid involvement in foreign wars will not offer military assistance, and to preserve neutrality may block American Jews from assisting Israel.
2. Based on polling, most Democrats and most Republicans favor the internationalist foreign policy dating back to people such as Truman, Eisenhower, and Kennedy – up to Reagan and the Bushes. However isolationists on the right and left have great influence on both parties, and based on the current situation, it is unknown which way both parties will turn.
