It comes in waves through out history. The West has had to fight them off several times. They have had to expand in different directions, to the South and the East. The difference now is that Christianity has weakened in the West. Their religion states that they will be in control and be wealthy because they follow Allah. We in the West have the money and the power and thus a great resentment. They should be the ones being blessed and are not. They see our moral decline and are even more enraged. Their religion says to destroy us and they think they can finally do it. No matter what happens now if they are not able to destroy us yet they will waite a hundred years send more muslims to live in our countries multiply and try and try again until they win unless something is done.
