If the US can back Jewish claims to Palestine (after it ceased to exist after 1700+ years) how are we going to tell other countries that their claims (substantially lesser time in historical past) are invalid??!! The world does not take our moralizing seriously because too many times the US is hypcritical. Example - Taiwan has the right to succeed from China but the Confederate States were crushed brutally. China does not allow the Christians to practice openly and freely, but a kid in US public schools can be suspended if he brings a Bible into the school. Worst we deal with Saudi Arabia as a close ally but they can kill Christians. George Washington understood the moral warp world outside of the US and warned us not to get into foreign entanglements. He was right. God gave us two ocean barriers, a large and rich land to build a prosperous and free society. Stay within it and we will come out ahead. Leave it and we will get bloodied and bankrupted.
If oceans are barriers what do they bar. Not the ships that the original settlers sailed here on.
Oceans bar travel the way that red lights can stop cars.
Bad example. It was Israel's land, and the original nations no longer exist, and there was no Palestine state, and the British gave land for a Jewish state, and the Muslims refused a deal that would have given them this:
