The operation in South Damascus is finished, everything in Damascus is now under control of the Syrian Army. Demining has started. The attacking forces are claimed to move to the South, Daraa. One can expect the next operation there.
I don't see any incidents in the last 9 years where a US stealth aircraft was damaged in any significant way,
Who cares? You have introduced general Russian military aircraft accidents into the discussion, so we compare now general Russian military aircraft accidents with general US military aircraft accidents, everything else is irrelevant.
Plenty of Russian fighter aircraft shot down in that time.
No. The SU shot by the Turks who was not prepared for this, the recent SU shot by some unknown special forces during a control flight over a peacekeeping zone, everything else was technical problems, not shots.
Israel has reportedly being using the F-35 in Syria to great effect, as has the US.
If they are happy with this, fine. The Russians have not tried to shot them, but have established rules of cooperation with the Israelis as well as the US to avoid any conflicts.
You still haven't given any evidence that the Assad regime was even behind the attack, nor an explanation why it hasn't claimed as much while supposedly trying to establish a deterrent.
Feel free to believe the Marsians were behind this.
There would have been no reason for the US to contact Russian officials and mention this to the public, if forces under Russian command/authority weren't involved.
The US does not know if Russian forces are involved on the Syrian side. There are Russian instructors in a lot of Syrian army detachments, so if the want to attack the Syrian army they cannot know and have to contact.
What little equivalent Syria has to the Viet Cong is mostly busy fighting against your boys. If you think millions of Syrians are going to rise up and storm US positions after all the times you've gassed and barrel bombed them, you must be high on Krokodil. Russia for its own part can barely afford to keep 5000 staff and service members there.
There is no need for millions. The millions of dead Vietnamese people are the result of US bombing civilians, not of fighting.
Arabs are not known for high morals, no comparison with Vietnamese, they prefer to fight on the side of the winner. But actually the winner in the internal Syrian fighting is Assad. In East Qalamoun whole organizations have simply switched sides. Much more simply choose not to travel to Idlib but to use the amnesty, but instead of staying without a paid job as a soldier now join the Syrian army. So, the majority of fighters is now behind Assad. In general, the situation is not that different - there was even a government of South Vietnam, which had a quite serious army too, so not only US vs. Vietnamese. Of course, the whole fighting in that time was much more serious in numbers. But this much smaller scale is about everything - on all sides, the morals of the US army is also much lower today than at that time, too much snowflakes there too. The US army is not at all a serious enemy except if they own the airspace, and if they do they simply bomb everything.
So, the most interesting question is about air control, and this is mostly political. Actually, the US can bomb on the East side of the Euphrat without any danger. This will remain so for some time - as long as there are terrorist gangs not yet under open US support. During this time, the partisan movement will be organized and start to act similar to what is done in Afghanistan - so, the US forces are fine if they sit like ducks in their bases, or in air, but whenever they are on the ground out of the bases they risk. After this, it is a question of time until the US boots on the ground are essentially worthless, because the don't risk to leave the bases.
Then, I would guess, there will be a game of shifting the Syrian red lines similar to what we see on the Israeli front. You will not hear much about this in the media, and in fact the Israeli game is an exercise for the game against the US. The differences are, of course, important, but not one-sided. On the one hand, Israel is much weaker militarily as the US, even if from a technical point of view there is no difference. On the other hand, Israel is much more interested to stand, to defend its own red lines. They have no option to run away.
How come you're always threatening nuclear war when the US contemplates hitting vital Assad regime targets?
Because there is some potential of escalation. Of course, bombing some Syrian targets is much less dangerous than what Clinton wanted (a no fly zone, which means targeting Russian airforce). But, if Russians are hit, even if by accident, the answer would be a US ship sinking. What follows? If Trump reacts firing all those who have started this hitting, nothing else happens. But if not?
And so Russian proxies retaliating against a nuclear power by attacking their forces on their home ground - that's ok with you as well.
Yes, definitely. Everybody has a moral right of self-defense, even Russian proxies if attacked by the US. Not?
You've suddenly acquired priorities far more important to you than the threat of nuclear war, apparently.
I don't think that this increases the threat of a nuclear world, as least not much. Given that the proxies do not even have nuclear weapons, the responsibility for such things resulting in a nuclear war is certainly on the US side. And, indeed, the right of self-defense has superiority over everything else. Else, MAD would be impossible.
According to you, Assad now has the capability of attacking Israel and defeating its forces, and the desire to do that - Israel is a nuclear power, and already paranoid. Whoever is setting Assad up to do that is risking nuclear war.
What Assad is doing now is retaliating against Israeli attacks, which is something very different from attacking. And completely justified by self-defense. Then, Israel itself is not even endangered by Syria, because there is a well-known and very simple way to make peace with Syria: Return the occupied Golan heights.
