We got Ali out in L.A. Thursday as news was pouring in about the attacks at the Kabul airport -- which left at least 12 U.S. service members dead -- and he predicts the violence will continue ... especially after America fully withdraws.

Like Ali points out, if this sort of mayhem is already happening, it's hard to believe it will go away once we leave.

The actor -- who's had guest roles on TV shows like "NCIS: Los Angeles," "SEAL Team" and "Madam Secretary" -- is asking everyone to send positive thoughts and prayers to the Afghan people ... because they're in a terrible situation right now.
