“Even if Iran, Pakistan and North Korea are not Russian adversaries, their current and projected nuclear potential could destabilize the regional situation. It could trigger a chain reaction of proliferation (Saudi Arabia, Syria, Turkey, Egypt, Japan, South Korea, Taiwan) that gives rise to a new missile threat for Russia,” Trubnikov said in an article included in the digest for an international conference on missile defense in Moscow.

History shows that relations with unstable states and radical regimes can rapidly deteriorate and their nuclear potential could become a real threat to Russian national security, Trubnikov said.

That is why Russia needs to work toward mutual understanding with the United States and NATO on the issue of missile defense, he said.
