The Arab nations have been warring against each other since the beginning of recorded history. The most obvious reason that western nations, particularly America, have become involved is oil.

It would be a lot cheaper in American lives and money to just pay top dollar for their oil and get ourselves, especially our troops and bases, out of the Arab nations. We have no business being there, especially against their wishes.

Of course I'm not a politician or statesman, just a working taxpayer.  One who bore arms in the past... not really to "protect" America, but, as I learned later, to protect corporate business.
