You do realize that the 7 laws of Noah are to be applied to the whole world all of mankind yes.

In Judaism the rightful punishment for idolatry is death. Now that means lots of dead Buddhists, Shinto, Hindus, etc. But more importantly Christians since Jewish commentary has generally said that Christianity is idol worship and is not monotheism(unless you are unitarian)
Now sure Jews are like 1 percent of the population and won't be able to wipe out millions. But the same argument applies to Muslims they won't be able to militarily invade and occupy Christian nations. So are we talking about what the religion says should be done, or what it is capable of doing?
Sure Islam is stronger, but the victory condition of each is different. Sure Islam conquering Christian lands is bad, very bad 2nd class citizenship and Dhimmitude. But at least Christianity is still allowed to be, and is not illegal.
