Let's see....
1. China has nukes - wants to take over the world
2. Russia has nukes - used to want to take over the world
3. N. Korea has nukes (see #1)
4. Iran will have nukes - wants Islam to take over the world
All 4 are allied together - sounds like a disfunctional family. It will be interesting to see how all this plays out in the future, not that I want to.
And people wonder why we want missile defense.
Believe me, if we let the liberals continue having their way in the US, Congress and a future President will roll out the welcome mat to our worst enemies.
