Soon as you mention anything about Israel that isn't seen as super positive, you are a nazi or anti Semite. Give me a break
This is basically true. The secular state of Israel cynically manipulates millions of evangelical Christians and others to support its policies implying the slightest disagreement is anti-Semitic, anti-Christian, anti-Biblical and only a step away from endorsing the Arabs wholesale slaughter of Jews.
Israel is a secular state with its own self interests which are not always in the United States' best interests. Their policies put Israel first (as they probably should) but are not always interested or concerned with the impact on America or her military or civilians.
When 241 US Marines of the 1/8th Marines were killed by a suicide truck bomber in Beirut, the Mossad was aware of the plot and tracked the truck closely right up to the time it detonated in the barracks there. A conscious decision had been made to not warn the CIA through back channels of the plot.
So it is wise to view any Israeli policies with a healthy dose of healthy skepticism.
