Our troops are spread so thin and our financial obligations are so strained in other parts of the world already, I sincerely hope we are able to avoid conflict in other countries. But, it seems that North Korea and Yemen are probably on the "next hit" list. With the leadership that we have, I am fearful that we will abandon Israel and that would be tragic. Israel is the only true democracy in that area and has been a long time supporter of our country. At the rate we are going into debt with China, they will soon have some in-put into our foreign relations with other countries (if they do not already). It is a slippery slope we are on.
I think it has to be Iran, looked for a while as it could be North Korea, but now Iran has taken center stage with their blatant statements over nuclear issues. With any luck maybe they will blow the hell out of all the middle eastern countries that are currently in this fray along with themselves. That of course is wishful thinking !
We can't get our butts out of Afghanistan and Iran/Irag, so we're waiting to throw our money in the next upset country since we are so almighty: Probably Israel.
