As I told a journalist before Trump’s illegal attack on Iran, if he directs the use of force unilaterally without congressional authorization, he owns the political consequences.

Going to Congress, seeking authorization for the use of force beforehand, and being (appropriately) rebuffed could save the President from such embarrassing military misadventures.

Sounds like a camp where you concentrate a politically undesirable population.

The inauguration crowd size was just the start.

The U.S. President tweeting cartoonish boasts from his Fox News (weekend) SecDef to bolster his illegal attack on Iran.

There’s a very good reason the U.S. Constitution does not/not assign the power to declare war to a single individual—to be decided upon based on mercurial whims and Fox News coverage.

The President took the United States to war with Iran without the authorization of Congress.   He claims the military operations were a success but is now refusing to brief the Congress or explain his actions in a timely manner.   Why is there a delay?

Important thread from my law school classmate @sergioperez.bsky.social.

Worth recalling that Congress enacted the legislation over Nixon's veto. Some lawmakers actually took their Article I responsibilities seriously.

"The WH says the assessment is 'flat-out wrong.'" It is a problem that the Big Lie is foundational to the current administration.

Ilegal? ✅ Unnecessary? ✅ Escalatory? ✅ Ineffective? ✅ Might backfire? ✅ Might be a reason the Constitution gives Congress, not the President, the power to declare war.

ICYMI My latest piece in @justsecurity.org analyzing the Trump administration's legal arguments in the new War Powers report on Iran and congressional options for responding to executive overreach. www.justsecurity.org/115398/trump...

Some members of Congress take their Article I responsibilities seriously.

A through line of Trump as president is his love of dropping big bombs in spectacular airstrikes. In Trump 1.0, it was the MOAB in Afghanistan. In Trump 2.0, it was the MOP in Iran.

Oh. If only there were some sort of alternative to (illegally) waving the magic military wand and hoping for the best. Like a negotiated agreement curtailing Iran's nuclear program—what you might call a JCPOA. www.cnn.com/2025/06/24/p...

One of many reasons that President Trump should have headed off Israel's attack on Iran in the first place. And that he should now do more than tweeting to bring about a durable ceasefire.

This is very good from @repdean.bsky.social. Also, the Libya “precedent” cited in this episode didn’t exactly turn out great.

✋ Former State Department war powers lawyer here. Some problems with the Speaker's remarks: --executive branch (even under Trump 1.0) has long treated the WPR as constitutional --some of the post-WWII military actions he refers to (eg Iraq, Afghanistan) had congressional war authorizations 1/n

Exceptionally informative and important analysis -- on the role of Congress and what precedent this moment may set for any U.S. President's ability to take the nation to war Thanks to @bcfinucane.bsky.social A must read

Read the latest from Non-Resident Senior Fellow @bcfinucane.bsky.social on Congress and the Trump Admin's new Iran War Powers Report 👇

Trump Administration’s Flawed Iran #WarPowersReport on Iran and the Need for a Congressional Rebuttal By @bcfinucane.bsky.social #CongressionalOversight www.justsecurity.org/115398/trump...

In the past, Trump has claimed to care about nuclear non-proliferation. Illegal threats and actual uses of illegal force (eg bombing Iran) combined with the undermining of US mutual defense alliances (eg NATO) increase the likelihood of such proliferation. www.justsecurity.org/109537/upend...

In other words, Israel did not act in lawful self-defense. And thus the Trump administration's claims that the US was acting in the collective self-defense of Israel when it bombed Iran also fails.

Once again, I'm grateful that the framers of the US Constitution gave the power to declare war to one man—to be wielded upon his capricious whims.

This former staffer for the Coalition Provisional Authority seems to like the latest illegal war over WMDs as well.

“There is no legality in these strikes.” Many people are saying. www.politico.eu/article/emma...

Anyway, is Jake Tapper working on a new book?

Another day and more foreign policy by tweet. Reminder that the George H.W. Bush administration blocked an Israeli retaliatory attack on Iraq in 1991 by refusing to deconflict the airspace.

War powers notification for US strikes on Iran —Article 2 as domestic authority —Cites national interest and collective self defense of Israel in eliminating Iran’s nuclear program — claims consistent with international law (More thoughts likely to come.) 1/n www.whitehouse.gov/presidential...

Which ought to raise further questions about why he decided to intervene militarily in the situation. Not sure this bolsters the supposed collective self defense argument for attacking Iran.

Not an ideal process for national security policymaking or US foreign policy. That said, if Trump wants a ceasefire he has tools, including critical military support to one of the belligerents.

“GOD BLESS YOU BOTH!” This day in foreign policy by tweet has been particularly surreal.
