So, back in 2001 the head of the Organization for the Prohibition of Chemical Weapons (OPCW) managed to get weapons inspectors into Iraq which pissed off the U.S. because it undermined their justification of the invasion.
In response John Bolton told the head of the OPCW:
You have 24 hours to leave the organization, and if you don’t comply with this decision by Washington, we have ways to retaliate against you. … We know where your kids live. You have two sons in New York.
