America has been an aggressor since before her inception often through gross manipulation. We aggressed against native America, Canada, Mexico, Spain, Vietnam, Iraq, etc.
Manipulations include the following: General Zachary Taylor was attacked after being ordered into disputed territory between the Nueces and Rio Grande rivers, Spain could not have benefited from blowing up the Maine, the Lusitania had munitions in her hold, there were no aircraft carriers at Pearl Harbor on 12/07/1941, the first Tonkin Gulf incident was provoked, the second incident didn't happen, I don't believe jet fuel fires in the upper floors could have thoroughly demolished the superstructures of the Twin Towers on 9/11, Bin Laden was allowed to escape from Tora Bora in 12/2001 (i), and there were no weapons of mass destruction in Iraq. Further, a nuclear capable or nuclear armed Iran will never be a nuclear threat to the United States.
Israel has shown its willingness to attack US ships in false flag ops as evidenced by its attack on the intelligence ship USS Liberty on 6/8/1967. The attack eliminated the possibility of US interference in Israel's planned attack on Syria the next day, 6/9/1967. Israel initiated military action on 6/5th and re initiated military action on 6/9th after Syria had accepted the UN cease-fire.
