Invade countries on false pretenses: don't impeach
Engineer coups to topple governments: don't impeach
Send weapons to murderous despots: don't impeach
Illegally surveil Americans on a mass scale: don't impeach
Temporarily withhold but then disburse some military aid: IMPEACH!!!

A useless act that only riles up Trump's base. They had so much to choose from and this is what they're impeaching him on.
