Out of the two super powers, Russia seems to understand its global obligations for disarmament. It has repeatedly urged the US side to resume earnest negotiations on arms control. Washington appears to have adopted a policy of procrastination to sow doubts about its intentions with regard to the New START treaty.
Having quit the nuclear accord with Iran, and the INF treaty with Russia, plus the Open Skies Treaty last month, Washington appears to be deliberately aggravating tensions and conditions of nuclear blackmail. The purpose seems to be to coerce both Russia and China into a new trilateral arrangement that benefits Washington’s geopolitical agenda of rivalry with Moscow and Beijing.
Given the record of backsliding by the Trump administration on international agreements, its entreaties to China regarding arms control should be viewed with deep skepticism.
