On Wednesday the International Court of Justice ordered the Trump administration to lift some sanctions on humanitarian aid to Iran.

The court ruling was a moral victory for Tehran, even though it was hoping for a more sweeping decision on the U.S. withdrawal from the nuclear deal. It had argued that U.S. sanctions, which were lifted when the agreement was implemented in 2016, violated the 1955 Treaty of Amity.

In response, the U.S. simply tore up the 1955 Treaty of Amity.
That's what you do, after all. When a treaty becomes an obstacle to getting your way, you tear it up.
This was the second time in a week that the ICJ got in our way.

Then, at a White House briefing, national security adviser John Bolton announced that the administration was reviewing all agreements that could subject the United States to future rulings by the court. He said Washington would withdraw from an amendment to the Vienna Convention on Diplomatic Relations, an “optional protocol” that allowed Palestinian officials to file a suit against the United States at the ICJ last week for moving its embassy in Israel to Jerusalem.

“The United States will not sit idly by as baseless politicized claims are brought against us," Bolton said. When asked about Tehran’s response, he replied that “Iran is a rogue regime . . . so I don’t take what they say seriously at all.”

Diplomacy! Who needs diplomacy when you have aircraft carriers and nuclear bombs, amirite?
Speaking of nuclear bombs, the Trump Administration is now considering tearing up one of the last significant nuclear treaties signed with Russia.

Defense Secretary Jim Mattis on Thursday said Russia’s deployment of nuclear-capable missiles in violation of an arms treaty is “untenable” and unless Moscow changes, the U.S. will have to match that military capability.

Speaking to reporters at the close of a NATO defense ministers meeting, Mattis said the U.S. is reviewing its diplomatic and military options because of Russia’s continued violation of the 1987 Intermediate-range Nuclear Forces Treaty.

"Russia must return to compliance with the INF Treaty or the U.S. will need to respond to its cavalier disregard of the treaty's specific limits," Mattis said in prepared remarks. "Make no mistake: The current situation, with Russia in blatant violation of this treaty, is untenable."

Mattis is right. Russia is in violation of the 1987 Intermediate-range Nuclear Forces Treaty.
However, Mattis didn't mention one little thing:

the U.S. violated the Intermediate-range Nuclear Forces Treaty first, 16 years ago.

On 13 December 2001, President of the US, George W. Bush gave Russia a 6-month notice of US intent to withdraw from the Anti-Ballistic Missile Treaty so that the US could pursue development of the program at that time known as National Missile Defense (NMD), which was already under way in potential violation of US treaty obligations.

On 10 February 2007, Russian president Vladimir Putin declared that the INF Treaty no longer served Russia's interests. On 14 February, the Information Telegraph Agency of Russia and Interfax quoted General Yuri Baluyevsky, the Chief of General Staff of the Armed Forces of the Russian Federation, as saying that Russia could pull out of the INF, and that the decision would depend on the United States' actions with its proposed Ground-Based Midcourse Defense missile defense system, parts of which the U.S. at the time planned to deploy in Poland and the Czech Republic. (Subsequently, the plan was altered and American MK-41 missile launchers were placed at new bases in Romania and Poland.]

Saying Russia violated this treaty with "cavalier disregard" is the height of hypocrisy. It requires the reader to be ignorant about how we got here.
