Never a good sign when the mission and objective is murky.
And the justification: it appears Israel was threatened. Not a lawful basis:
“(c) Presidential executive power as Commander-in-Chief; limitation
The constitutional powers of the President as Commander-in-Chief to introduce United States Armed Forces into hostilities, or into situations where imminent involvement in hostilities is clearly indicated by the circumstances, are exercised only pursuant to (1) a declaration of war, (2) specific statutory authorization, or (3) a national emergency created by attack upon the United States, its territories or possessions, or its armed forces.”
Once again, the rule of law (US and International) should matter, especially when we use military power. There’s a reason why our Constitution requires the consent of the American people.
