I like this, and so will allies under threat when these states go fully nuclear:
The Trump administration intends to develop a "state of the art" missile defense system to protect against attacks from Iran and North Korea, the White House said in a policy position posted on its website on Friday.
Sadly, Russia is already deeply upset at our thin defenses in Europe and China is deeply upset at South Korea's planned deployment of American-made anti-missile defenses (THAAD).
Both prefer to have America's allies vulnerable to their nuclear missiles.
And not just vulnerable to destruction since even planned improvements in missile defenses won't do more than defend against a small attack.
No, the Russians and Chinese want to be able to efficiently nuke our allies without the cost of some of the warheads they launch getting shot down.
So enjoy any happy "reset" dreams while you can. Russia and China won't go along if it involves anything that lessens their ability to nuke people.
UPDATE: Oh, and I should note that the Russians and Chinese really don't like powerful American-built radars peering into their territory. So there is that aspect, too.
