Why Is the West Preparing for War?

Paul Craig Roberts

One result of the just concluded NATO Summit is Germany’s decision to host US intermediate-range missiles. Prior to 2019 when Washington cancelled the INF Treaty, the treaty prevented such deployment.

The INF Treaty was signed by Ronald Reagan and Mikhail Gorbachev on December 8,1987, and the treaty was ratified on June 1, 1988. The treaty was part and parcel of ending the cold war. Reagan called the treaty a “step toward a safer world.”

“The 1987 Intermediate-Range Nuclear Forces (INF) Treaty required the United States and the Soviet Union to eliminate and permanently forswear all of their nuclear and conventional ground-launched ballistic and cruise missiles with ranges of 500 to 5,500 kilometers. The treaty marked the first time the superpowers had agreed to reduce their nuclear arsenals, eliminate an entire category of nuclear weapons, and employ extensive on-site inspections for verification. As a result of the INF Treaty, the United States and the Soviet Union destroyed a total of 2,692 short-, medium-, and intermediate-range missiles by the treaty’s implementation deadline of June 1, 1991.”

Blaming Russia the Trump administration pulled out of the treaty. The consequence was to kill the nuclear disarmament that the INF Treaty began and to renew the arms race. If I had to bet I would say Washington’s withdrawal was a consequence of the US nuclear industry needing the source of profits that the arms race provided and the neoconservatives’ determination to revive US hegemony through the buildup of force. If Russia was truly out of compliance, Trump’s focus should have been to work to bring Russia into compliance, not terminate the treaty. The efforts of several American presidents and Soviet leaders in the 20th century to defuse tensions and to build trust were squandered by Washington in the 21st century........more.........
