“America First” means foreign countries LAST. Remember that Russia, China, Iran and North Korea are allied. There already are Russian troops stationed in Syria (referenced in reports of foreign troops supporting Hebzolah in Syria ready to enter Lebanon and fight the Israelis). If Trump wins, he will give much sympathy for Israel, but nothing that will meaningfully stop the Russia/Iran/China axis from attacking. And remember that Israel is hopelessly outnumbered, and receives a large amount of its arms from the Americans. Of course one could hope for a miracle, perhaps in zechus of Israel cracking down on Torah education, banning abortions and LGBTQ, etc. (I am being sarcastic). The Israeli might be able to survive if they give up their first world standard of living (which many if not most Israeli Hareidim don’t enjoy), and are prepared to fight without American aid – but that might be too little, too late.
While Kamala (and her movement, the WOKE Progressive wing of the Democrats) only hate Israel, they are not likely to meaningfully oppose the “axis” since they prefer to focus on domestic matters and WOKE policies, rather than rebuild national defenses which have been seriously weakening for the last 16 years, so if those who depend on the United States in Europe or Asia which to survive, they need to be prepared to make the sacrifices necessary to defeat their enemies.
