I wish everything in politics and media campaigns was simple black and white, unfortunately it is not. But you are welcome to believe it is. (You are also welcome to give me more negative rep, for speaking out my mind.)
(US or Saudis invading Syria gains the US regime change and as result loss of Russian navy base in Syria, plus gain of regional influence to Saudis over Iran. It is murky politics, but basically Iran is run by the shia and supposedly they are allied with Syrian alawite government. Also, US ally Israel in the region gains the Golan Heights aka Syrian Golan permanently - if the new regime in Syria permanently denounces its rights to the land. I mean, it is all very very regional but at the same time very important on the grand scale of things. Do some research of your own on the net if you wish. )
"Gains the U.S. regime change". Hmm, to what exactly? True, American military intervention would spell the end to Assad, but what comes after that, and what exactly about it is pro-American? Do you know anything at all about the people actually fighting Assad and his regime? Do you know anything about their own political leanings? About their leaders or why they're fighting? Do you know that a good portion of the rebels are radicalized Islamist extremists who, while attempting to depose Assad, or simultaneously fighting each other? Do you know that al Qaeda is fighting Assad, as are there splinter group ISIS? Both organizations have been very, very open about their desire to create an Islamist state adhering to 6th century Muslim law. Why would the United States want to aid that vision? Last I checked the U.S. and al Qaeda don't exactly get along.
Syria is a huge problem for America primarily because there are no easy outs for them. If they intervene they rid the world of Assad, who by the way is one of the most evil people alive (I've noticed you've omitted that from your...logic or whatever), but then would throw Syria into an even bigger civil war as the rebels turn on one another. If they do nothing countless numbers of innocent people continue to die. It's a total lose-lose situation for the United States.
Also, you haven't even mentioned the talks of Geneva 2, the deal engineered by Russia and
backed by the United States, which fell apart like a cheap tent. You haven't mentioned that the chemical weapons removal plans, a huge part of any peace settlement, have been an unmitigated disaster as Syria has failed to meet any disposal deadlines whatsoever.
You've totally left out Russian motivations for keeping Assad in power, largely the vast quantities of weapons sold to him by Moscow. You haven't said anything about the Shi'a/Sunni conflict and how that plays into things. You haven't even mentioned the crimes of Assad. Both of your anti-American diatribes have been completely void of any detail or nuance regarding the situation.
So yes, I understand regional politics surrounding Syria, and I understand that they're murky at the best of times. In fact I know this issue pretty well. You are absolutely entitled to your opinion and I'm aware that I've come across pretty harsh on this topic, but it is exhausting seeing the United States being bashed over a scenario where they have consistently proven to be one of the only altruistic players in the conflict, especially when that bashing is, I'm sorry, woefully misinformed.
It is like Russia cannot do anything right - because it is never enough.
That's what the world (not just the U.S.) tends to think when you've been the bad guys of the last 70 years or so. That's the perception created when the Russian dictator completely perverts the will of his own people and the democratic process.
And lastly, your implication that the American media is this devious arm of the
democratically elected U.S. government, in contrast to Putin's near complete control of the Russian media, is laughable.
