The US was tragically attacked at the World Trade Center in 1993 and on 9/11 because of US support for Israel’s brutal oppression of the Palestinians (look up ‘Israel as a terrorist’s motivation’ in the index of James Bamford’s ‘A Pretext for War’ book and take a look at the ‘What Motivated the 9/11 Hijackers?’ youtube linked on the upper right of http://NEOCONZIONISTTHREAT.COM ) with the US then invading Afghanistan and Iraq as a result of such!:
