To be clear, I've never used this for POTUS, but today it is well deserved.

“We’re not inflicting pain on these fu..ers. When people kill us, they should be killed in greater numbers.” Then, with his face reddening, his voice rising, and his fist pounding his thigh, he leaned into [the national security adviser] as if it were his fault: “I believe in killing people who try to hurt you, and I can’t believe we’re being pushed around by these two-bit pricks.”
That was Bill Clinton in 1993, after American soldiers were killed in Somalia.
