[Citizen of the United States]

I will say only this:

May the LORD rebuke them.

[Pyro7480]

Here's a prayer for such occasions:

Prayer to the Archangel Michael:

St. Michael, the Archangel, defend us in battle. Be our protection against the wickedness and the snares of the Devil. May God rebuke him, we humbly pray, and do thou, O Prince of the Heavenly Hosts, by the Power of God, cast into Hell, Satan and all the evil spirits who prowl about the world, seeking the ruin of souls.
Amen!
