I am very familiar with those treaties.
Something interesting about the INF Treaty. China never signed it. So, the PRC has missiles (and TELs) banned in Russia and the US. With the 7/16/2001 Treaty, the door has been opened for vast degrees of military cooperation. So, imagine one day, Bout's planes land in the PRC, TELs with DF-21s roll on, and the planes then land in Western Russia. Just a thought ..
Um, all due respect and what not, but INF was a BI-LATERAL TREATY. Same with SALT I, SALT II, START I, START II, and INF II.
Your scenario re: China and Russia would put Russia in violation of the treaties they signed, ratified and implemented. Plus, you're seriously overstating the "cooperation" btwn China and Russia. BTW, all Russian politicians understand perfectly that if they want to "trouble" the West they can pretend to play footsies with China. NExt thing you know, the West (mainly the mamby-pamby Europeans) are making nice to lure Russia to look toward Europe and not China. I do not know ONE, not ONE Russian who considers China a) reliable, b) a friend, c) a partner, d) an ally, and e) trustworthy.
