Dee, I guess it depends on your definition of "war". If I remember correctly, we gave Iraq a pretty good ass whippin in the Gulf War. And the actual war part of this current Iraq situation didn't turn out so well for the Iraqi military either.
Call it a skirmish if you like, but Serbia called uncle pretty fast when Bubba was busy bombing the Chinese embassy there.
Anyway, you say this country has no friends. I think you need to ask Canada, Australia, Poland, Japan, South Korea, Italy, Columbia, Chile, Israel, Kuwait, and on and on. Personally I couldn't care less if this country, or that country doesn't consider us a friend; what you can count on is they'll be friendly enough when they need our help.
Back to the original theme of this thread: Most of us would like to see the borders secured; presumably by some act of Congress. As if some new law has to be enacted. It is already illegal to cross our borders without going through a proper checkpoint. I is already illegal to be in this country without the proper documents. So what are we really talking about?
Obviously, there isn't going to be an effective wall built all the way across our southern border and for sure not on our northern border. And I don't think we could ever have enough border guards to do the job. So where does that leave us?
We must enforce the laws that are already there. Hiring illegals must not be tolerated. Allowing illegals to take advantage of our medical system, must be stopped. No illegal kids in our schools. In the short term, it might be necessary to put troops and or armed volunteers on the southern border. Yeah, wait for that to happen.
