The support is unconditional, so the money is going to continue to flow to Israel, not matter how much violence they unleash in the middle east.
Who would have thought that the strong alliance between Europe, Canada and the US would suffer a setback? We are now experiencing a time when Europe is not sure of the actions or inactions of Donald Trump. The moral of this lesson is that no relationship is forever. Different US governments have unconditionally supported Israel regardless of their violation of human rights and international laws. Maybe, a government might be elected one day that will see the excesses of Israel and decide to call them to order.
I get what you mean, but you need to take a look at how there are some many lobbyist and organizations in Washington which are highly funded so pro-Israel politicians (both Republican and Democrat) are elected for public office, being the biggest example the AIPAC. Which such big organizations interfering and lobbying in favor of Israel without interruption for years in the political capital of the USA, they would not allow a president who is anti-Israel to reach the presidency, that person would barely get any funding from donors.
So, I don't ever expect to see an administration of the United States which decides to stop supporting Israel economically and militarily, there is simply too much money being used to convince politicians to support Israel and also campaigns to wake up pro-Israel sentiments in the minds of the collective of the USA.
