So you have an explanation for the centuries of terrorism and war waged by Islamic extremists against the West prior the establishment of Israel.
Here is a map of the Muslim invasion of Europe over time to provide some context with commentary and information in context.
Ancient history is irrelevant. The Arab world was favorably disposed towards America after WWII, until Israel started its ethnic cleansing campaign in 1948.
400 killed, injured as Israel bombs Jabaliya refugee camp in Gaza At least 400 Palestinians, mostly women and children, have been killed and injured after Israeli airstrikes hit the Jabaliya refugee camp in the Gaza Strip, amid the regime’s ongoing bombing campaign against the besieged territory. Gaza’s health ministry announced the death toll on Tuesday. The Palestinian interior ministry also said the strikes had left 400 dead or wounded in total. Iyad al-Bazum, interior ministry spokesperson, also noted that US-made bombs have targeted residential homes causing a "massacre," adding that an entire residential complex had been destroyed in the attack. “These buildings house hundreds of citizens. The occupation’s air force destroyed this district with six US-made bombs. It is the latest massacre caused by Israeli aggression on the Gaza Strip,” he said, calling on the international community “to act immediately to stop Israel before it is too late.
"The Arab world was favorably deposed towards America after WWII". LOL I think not. The Arab world was also not favorably disposed towards European nations such as France and Great Britain (you know, America's allies) who they viewed as occupiers. They considered the U.S. just another western nation similar to France and Great Britain.
As I outlined earlier today, at least Israel takes immediately responsibility for the attack on the Jabaliya refugee camp in northern Gaza. Unlike Hamas who still does not admit their rocket hit a hospital parking lot.
