Because he was stupid and believed the warmongering propaganda. Iraq should've never been invaded, they were never a threat to the U.S. and were keeping Iran in check. (The mullah's feared Hussein, that crazy bastard.)
Why did US invade Vietnam?
Do you want the entire history or the typical "to fight communism" response? Pick one.
Why did US invade Afghanistan?
To take out Osama bin Laden, the mastermind of 9-11 who along with his co-horts were shielded by the Government of Afghanistan and later in Pakistan (where he was eventually killed.)
Immediately after killing Bin Laden in Pakistan we should've left Afghanistan, and unlike that fucking moron Biden, should've taken all our equipment with us. Nation building should never be done by a military who's sole purpose is to break things and kill people.
Govt of Afghan did not send pilots to send in tall buildings.
They harbored and shielded those who did and if you refuse to acknowledge that fact, this discussion is over.
Do you know history of Ukraine & Russia going back 300 years?
Yep, do you want all of it? The history of the past 300 years is irrelevant. Ukraine is a globally recognized Sovereign Nation. Russian invasion is wrong. The sane world (exceptions: China, Iran, North Korea, Syria) stand against it.
Hahaha you are so confused.
per your argument, Russia can not attack Ukraine because it is a SOVEREIGN country!
Well, we attacked CUBA by executing a naval blockade around Cuba, thus infringing the rights of SOVEREIGN county for free access to its ports. May be you are too young to remember it, but it was during JFK admin.
Do you know why we did it? Because we did not want missiles stockpiled in Cuba only 90 miles away from our shores. That is exactly why Russia is attacking Ukraine because Ukraine is NOT 90 miles away from Russian border, it is RIGHT ON Russia border. And Ukraine has been pushing to join NATO and stockpile war weapons in Ukraine. Russia does not want adversary country on it’s borders. It was OK for us to attack Cuba but not OK for Russia to attack Ukraine?
