The INF Treaty hamstrings the U.S. Trump is right to leave it.
The Trump administration has announced that it plans to withdraw from the Intermediate-range Nuclear Forces (INF) Treaty of 1987. This treaty banned the United States and Russia from possessing any ground-launched ballistic and cruise missile systems with ranges between 500 and 5,500 kilometers (300 to 3,400 miles). The administration’s decision is sure to elicit a cacophony of criticism, but the truth is that the United States should no longer tolerate the INF status quo. The reasons basically boil down to two: Russia appears unwilling to give up the systems that violate INF (meaning INF is essentially a dead letter), and, more important, the United States no longer benefits from a ban on ground-based intermediate-range systems — but because of China, not Russia.
