President Donald Trump's decision to launch a military strike on Iran's nuclear sites without fully consulting the U.S. Congress layered a partisan approach onto a risky action, particularly because the White House briefed top Republican leaders beforehand without doing the same for Democrats.

Authorizing foreign wars is the job of U.S. lawmakers, but recent presidents have stretched their own powers to engage in global conflicts.
