Western Governments, Syria and threat of force

It seems that threatening to use force against other sovereign States has become "normal" for Western Governments and part of their foreign policies.

Although the US and Russia reached an agreement on stripping Syria of its chemical weapons, and Syria acceded to the Chemical Weapons Convention (it will enter into force for it on 14 October 2013), the US said that “military option remains on the table”. Also, France’s Hollande stated that “the use of force against Syria is critical”.

So, how could the US and France talk about international peace and security when they both say that “using force against Syria is still an option”? The threat of force against another State itself threatens international peace and security, and also violates international law, particularly Article 2(4) of the UN Charter.
