【明報專訊】LAST week US President Donald Trump announced the withdrawal from the Intermediate-Range Nuclear Forces Treaty (INF) signed with the Soviet Union in 1987 on the grounds that Russia had repeatedly violated the treaty and that China, which has not signed the treaty, was able to enjoy a lot of advantages in the sense that it could conduct research on intermediate-range missiles and deploy a lot of them with free rein. Though Europe has expressed grave misgivings about the US's withdrawal, Russia's reactions have not been as strong as expected. John Bolton, the National Security Advisor of the US, has even forged a consensus over a new summit between Trump and Vladimir Putin next month in Paris.
