Hate is evil and never solves any problems. One of the truly sad things about evil is that it snowballs as groups and people keep getting back at each other. So one horrible act can unloose many other acts of evil. If we respond to evil with our own acts of hatred, we are letting evil win. God has already won the ultimate war against evil, and we are to be living symbols of that victory.
Some people are very happy when the United States suffers.
One reason is because the United States is the world's most powerful country, and we don't always use our power in the right way. Sometimes our power can hurt other people and other countries. Nothing makes what was done right. But our country must ask why people in other countries hate us, and we must listen when people tell us how our power has hurt them. The world needs God's people more than ever.
