Within days of each other, North Korea said it is speeding up its nuclear weapons program, South Korea pushed ahead with nuclear-powered submarines, Iran recast its military strategy as a way to push US troops out of the Middle East, and analysts linked small nuclear reactors to the same goal.

President Trump ordered the Pentagon to reduce planned joint military exercises with South Korea, an ally the US has long worked with to deter North Korea.
Four defense stories this week point to the same problem: governments have money and plans, but not enough factory capacity to build weapons fast enough.
Ukraine's president says Moscow and Pyongyang have agreed to raise North Korea's troop presence in Russia to between 30,000 and 50,000 — a scale that would make it Russia's largest foreign troop contribution and give Pyongyang combat experience with implications far beyond Europe.
