If can politely disagree with you here... First of all, Putin isn't acting in the interest of international law. Putin is acting in national interest: Russia's sole Mediterranean naval base is in Syria--and in the region in which the Syrian controlling group reside. On top of that, Russian arms contracts, both in progress and existing, value over $5,000,000,000. This is vital to the Russian arms industry; already, $13,000,000,000 has been lost due to sanctions against Iran, and $4,500,000,000 in cancelled Libya contracts. Russian companies' investments in Syrian infrastructure, tourism, and energy were valued at $19,400,000,000 in 2009. Second, these claims that "the opposition may have released the chemical weapons" are completely ungrounded. Both sides are spreading incredible lies about each other; the FSA blames attacks claimed publicly by Al-Nusra (Syrian arm of al-Qaeda) on the government, for example. Few claims are to be trusted. HOWEVER, the UN inspectors will provide evidence that points to Assad's regime. Given, the evidence is exclusively circumstantial, and the report will not directly accuse Assad of using chemical weapons. However, there is also this evidence, which I have researched myself: There are four chemical weapons production facilities in Syria. Three are in areas of regime control, one is in an area in disputed control (Aleppo). There are three chemical weapons storage facilities in Syria, and all of them are in areas of regime control. Evidently, the regime capacity for chemical weapons attacks are vastly superior to opposition and FSA capacity. Finally: On the actual strike against Syria. Syrian regime actions up until the usage of chemical weapons are regrettable, but do not violate international law nor do they necessitate any action by advocates of such law. However, the usage of chemical against the Syrian people by the Syrian regime is a direct violation of international law. As President Putin says, international law must be enforced. A red line has indeed been drawn; not by the USA, but by the UN. If the Russians are intent on preventing any UN action, then action must be taken by other means. Assad may continue his fight against the opposition, the FSA, and al-Nusra. But he may not, in my eyes, continue his usage of chemical weapons.But I'm not sure it matters why he's right, just that he's right in this case (and I'm convinced he is right). We have no business getting into this fight. It's a no win for us any way it turns out. We should stick to the business of humanitarian aid here.
U.N. inspectors have collected a "wealth" of evidence on the use of nerve agents that points to Syrian President Bashar al-Assad using chemical weapons against his own people, according to a senior Western official.
