The Intermediate-Range Nuclear Forces Treaty (INF) was a treaty signed by the United States and the Soviet Union designed to eliminate the conventional ground ballistic missiles as well as the cruise missiles with ranges of 500 to 5,500 kilometers. However, in recent years, Russia appears to be moving with their program to produce missiles that violates that arms control agreement.

In July 2014, the Obama administration informed that Russia violated the treaty due to the fact that Russia was conducting flight test of the missile.

American officials are now concerned with this fact and are considering the ways to deal with this issue. They have tried to impose economic sanctions, but, they have not worked effectively in order to stop Russia from violating the treaty.

Russia in the past has suggested to get rid of the treaty, and also, the treaty was signed by the Soviet Union, but it still applies to Russia and other regions. The violation of the treaty is in the interested of the United States and also makes American-Russian relations to deteriorate even more. American officials are still trying to figure out a way to make Russia comply with the treaty.
