You trust your nation? I suggest you look up these lies and deceptions before you run with that.
1. Project MKUltra, also called the CIA mind control program, is the code name given to a program of experiments on human subjects, at times illegal, designed and undertaken by the United States Central Intelligence Agency.
2. Operation Northwoods was a proposed false flag operation against the Cuban government that originated within the U.S. Department of Defense (DoD) and the Joint Chiefs of Staff (JCS) of the United States government in 1962. The proposals called for the Central Intelligence Agency (CIA) or other U.S. government operatives to commit acts of terrorism against American civilians and military targets, blaming it on the Cuban government, and using it to justify a war against Cuba.
3. Colin Powell has called his 2003 speech to the United Nations, laying out the Bush administration’s rationale for war in Iraq, a “blot” on his record. The speech set out to detail Iraq’s weapons program, but as the intelligence would later confirm, that program was nonexistent.
If you're interested in more, then I can list hundreds of examples.
