Not yet it isn't. But I'm not so sure that we don't have a big problem here on our own soil.
Moslems now account for more than 5% [14 million strong] of the population and they aren't aborting anyone. And if anyone has noticed there is a "push-pull" tendency of islamic immigration which will play a major role in our future. In every other country they've immigrated to they at first live quietly, respecting the laws in the land which they live. However, as their birth-rate surpasses that of their Christian and Jewish neighbors, they become a sizeable minority with a big voting constituency, a fact that won't go ignored by pandering politicians [or by Bush who says that we aren't at war with Islam] who want to be re-elected.
From a small minority, these moslem citizens use their vote, and demand to be heard and to influence their neighbors more and more to accept "Islamic" rights, and then finally the aggressive, mutant form of Islam.
Islam is already a threat here at home because as they reach 20% and 30% of the population, it will utilize American democracy just as Hitler utilized Weimar German Democracy to ascend power or act as power brokers within the system and then eject the democratic system which is unacceptable and unreconciled to Islam. That can happen within two decades. I guess we'll just have to wait and see.
France is looking at the same problem. Moslems now make up 15% of their entire population. That is huge considering that France is not that big of a country to begin with. Everywhere the moslems have gone they have had a population explosion--and with their sheer numbers they use the democratic system to get themselves elected and win power--then out comes the radical strain of Islam that can't be rectified with democracy.
The problem I have with your characterization of all Muslims as warlike is that it is an over-generalization that isn't even true for the most part.
I think moslems are as much a victim of Islamic violence as everyone else, and I have nothing agnist them as a people. I have no military solution to offer. The only thing I can see is to pray for a revival of traditional Judeo-Christian values and to preach the Gospel to those on our own soil. I know many people disdain my belief system, but it is the foundation of this country and the root of our freedom.
