Did the US have to support a Muslim Brotherhood takeover of Egypt? That is clearly what we have done.
I don’t think you understood what happened in Egypt. A man had ruled Egypt for 31 years and even the cats, dogs and mice in Egypt wanted him to go.
I guess you have never lived under a dictator, I have. It is a nasty experience (it does not matter whether the dictator is supported by either the US or the Soviet Union).
What exactly did you want the US Government to do? Or what exactly could the US Government had done?
The Muslim Brotherhood has not taken over Egypt - and short of invading Egypt there is absolutely nothing the US Government can do to prevent the Brotherhood from taking over, if that is what the Egyptian people want.
The US Army invaded and occupied Iraq only to replace a very nasty secular dictatorship with Iran lite. In Afghanistan.....
The best you can do is pray.
