What most everyone on this thread seems to have either forgotten, or never understood in the first place, is that Russia, unlike the United States, was invited by Syria to enter the country. Therefore, according to U.N. agreements, Russia is there legally; the United States is not.
According to UN agreements, which the United States was party to, the U.S. had/has no right to enter the country, nor to fund the Syrian opposition, regardless of what the U.S. was alleging was occurring within Syria.
Therefore, the United States is, and has been, committing another international war crime with every move it makes. But, the U.S. controls the U.N. like a puppet. Therefore, the U.S. will never be charged.
All of you folks worried about nuclear war ought to listen very attentively to redravensounds; she's a former U.S. nuclear armarment expert. She knows what she's talking about.
And, you ought to read A Russian Warning; and, at least glance at How Russia is preparing for WWIII.
Please note, in the first article, the following statement:
"We also appeal to the American people to take peaceful but forceful action to oppose any politician or party that engages in irresponsible, provocative Russia-baiting, and that condones and supports a policy of needless confrontation with a nuclear superpower that is capable of destroying the US in about an hour."
The authors of these articles, who are Russians living in the U.S., are very familiar with the conventional and nuclear weapons capabilities of both the United States and of Russia. Please consider listening to them.
