Are you a Christian? WE as Christians hold no animosity against non-Christians. We sympathize with them in their losses, just as we would if they were Christians. But, they are the enemy of the cross of Christ, if they don't accept Jesus as the Son of God, and the salvation He provides by being Such. As an enemy, any Muslim is an enemy no matter how much we sympathize with them. They are especially so if they have formally rejected Jesus as their Savior. The interesting thing is, most Israelis fit that category, as well. An additional point is, we as Christians need to make sure that they have heard that Jesus is God, and that He offers them salvation right along with us.
