Some are worried, but I think China is relatively innocuous, a peaceful nation.
But, just to keep the West at ease, if China ever decided to commit evil upon the West, the Orthodox Israeli people around the world will protect the West. Secular Israeli people barely have any children, but the Orthodox have around ten children each. They are forbidden to fight in the Israeli army or work in a real job, but they have the power of prayer: imagine all the large Orthodox families around the world uniting in prayer for G-d to destroy China IF China decided to become evil. China would not stand a chance.
