Michael Flynn's statement today, addressing the U.S. sanctions on 25 individuals and entities related to the Iran missile test.

The days of turning a blind eye to Iran's hostile and belligerent actions toward the United States and the world community are over.

Secretary of Defense Mattis is on his first foreign trip. At a stop in South Korea, according to the AP, he tells the North to watch out:

America's commitments to defending our allies and to upholding our extended deterrence guarantees remain ironclad: Any attack on the United States, or our allies, will be defeated, and any use of nuclear weapons would be met with a response that would be effective and overwhelming.

Nikki Haley strongly condemned Russian actions at an emergency U.N. meeting today about recent upticks in violence in the eastern Ukraine Donbass region between Russian-backed separatists and the Ukrainian army.

The dire situation in Eastern Ukraine is one that requires clear and strong condemnation of Russian actions... This escalation of violence must stop.

She called on Russia and Ukraine to uphold the Minsk I and II agreements to restore the ceasefire and pull out heavy artillery from the disputed region, which has been in turmoil since 2014 when Ukraine President Viktor Yanukovytch was ousted and Russia annexed Crimea. Haley added that U.S. sanctions against Russia regarding its "occupation" of Crimea would remain in place until Russia returns control over the peninsula to Ukraine.

Why this matters: Haley used clear and strong language against Russia — much stronger than Trump used on the campaign trail, and much stronger than the U.S. State Department language released the day after fighting broke out this week. Remember, Trump previously said he might recognize the annexation, and experts have been saying the new clashes may have been a test from Russia to see whether Trump's team is willing to be friendlier to Russian interests.

Today the Treasury Department's Office of Foreign Assets Control published an amendment to Obama's sanctions against Russia. It now will "authorize certain transactions" with Russia's Federal Security Service (FSB), the KGB successor intelligence service. The amendment caused a lot of quick chatter on the internet that Trump was rolling back Obama's sanctions. NBC reports the changes were "technical."

White House spokesman Sean Spicer confirmed the U.S. is "not easing sanctions."

Update: Senator McCain added, "our initial look at it is it's a largely technical fix."

Prime Minister Theresa May's white paper on Brexit negotiations stresses the importance of trade, which has risen to about 60% of British GDP in recent years.

Why it matters: Theresa May may struggle to keep borders open to trade, but as closed to immigration as her base demands. The United States, on the other hand, is a much more closed economy. where most economic activity occurs intra-nationally. Trump has a little more wiggle room to play hardball.
