The US invasion of Iraq always reminds me of someone who takes action brainlessly and impulsively without ever thinking of the consequence. When US first bombed Iraq, it felt so safe and so good, like a six-grader slaps the face of a first-grader in primary school. The U.S. was certain that it could do whatever it pleased on the land of Iraq because there was no threat of nuclear weapon or something like weapon of mass destruction in Iraq.
It does not care how other nations perceive it. However, if anything, the US invasion of Iraq woke up everybody around and sent a clear message to them that they got to arm up to the teeth with something that the U.S. is afraid of. Otherwise, they will end up like Iraq, if they happen to have rich oil deposit.
This is what Iran is doing at the moment and much more, its challenge has not been met so far. The U.S. only powerlessly recognizes the coming of a “military dictatorship.”
A person is very much like a nation. If he does not think about the percussion of his action, he will eventually end up like the U.S. today, ensnared in two wars and threatened by Iran. As with everything, always remember you reap what you sow. Nothing comes from nothing.
