National Security Adviser Michael Flynn announced Wednesday that President Trump is putting Iran "on notice" after reports that the nation had tested ballistic missiles. It is unclear what "on notice" means at this time, although there will be an additional press briefing by the White House National Security Council later Wednesday.
In 2015, former President Barack Obama struck a deal with Iran limiting its nuclear program. "President Trump has severely criticized the various agreements reached between Iran and the Obama administration, as well as the United Nations, as being weak and ineffective. Instead of being thankful to the United States for these agreements, Iran is now feeling emboldened," Flynn said in a statement announcing the decision.
