Is Israel really our friend?

How come they attacked and killed 167 of our soldiers on purpose on the USS Liberty in 1967? How come Doug Feith a dual citizen Israeli falsified intelligence in order to get American soldiers to invade Iraq and die for Israel? Why doesn't Israel fight it's own wars? Why must we spend American blood and money for a parasite country that never has once paid back any of the 6 trillion dollars that we lent to them? What benefit has America gained from its relationship with Israel? Since I read the Talmud I completely understand the behaviors of practicing Jews. They believe all Gentiles are expendable in order to promote Jewish Supremacism.
