Jerusalem has been the principal city of the Jewish people for millennia. Only the perversion of Western diplomacy and Muslim bigotry could have a problem with recognizing Israel’s selection of a capital city.
What other capitol city is claimed by two rival forces?
The Jews’ eternal capitol is and has always been Jerusalem and when Jews pray (3 times a day) anywhere on the planet, they face Jerusalem.
To the Muslims Jerusalem comes in 3rd place in terms of importance. Muslims pray 5 times a day and face Mecca & Medina and NOT Jerusalem! Actually they face their rear ends towards Jerusalem’s Temple Mount!!
The fact that they have successfully raised the importance of Jerusalem (or as they call it Al-Quds, the Holy) to the epicenter of their struggle to kill all the Jews is factually irrelevant but then again, since when has their truth been important to the Arab-Muslims?
