God's will is often not carried out. The question is what does God do when it isn't, that is what we should worry about.
Luther’s explanation to the petition,Thy will be done on earth as it is in heaven: “The good and gracious will of God is done indeed without our prayer. But we pray in this petition that it may be done among us also. How is this done? God’s good and gracious will is done among us when God breaks and hinders every evil counsel and will which would not let us hallow God’s will nor let His kingdom come, such as the will of the devil, the world, and our flesh, but strengthens and preserves us in His Word and faith until our end. This is His gracious and good will.”
Pray that every evil counsel and will would be vanquished and that our President will be able to strengthen and preserve our nation.
