"He has excited domestic insurrections amongst us, and has endeavored to bring on the inhabitants of our frontiers, the merciless Indian Savages, whose known rule of warfare, is an undistinguished destruction of all ages, sexes and conditions."

Excited domestic insurrections - check.
Endeavored to bring on merciless invaders whose method of warfare is undistinguished destruction - check.

Change "Indian Savages" to "Illegal Aliens" and it's 100% spot on today.
