The US is always looking for a war. Going into countries without the right to do so (only because they're the US Army) and doing what they want and making up rules.
I read somewhere that last year the US spent for war something like around 140 trillion dollars, when world hunger could be ended with a su around 90 trillion.
War is the best business that the US is having, so of course that they are trying all strategies possible to make it happen.
