Russia arms the Syrian government, as it has done so for 11 years (and for decades before that as the USSR) and so is profiting from the current war being waged by the Assad Ba'athist dictatorship against Syrians who oppose him.
You'd think that the so-called "peace" movement would be protesting. That Russian embassies worldwide would face pickets, that Russian flags would be burned, led by the Westerners who did just that against US embassies and flags when the US intervened in Iraq.
Syrians are doing so, but the "peace" activists are strangely uninspired. Why?
A visit to the "Stop the War Coalition" (STWC) website says it all. A big focus on backing Iran, that great harbinger of non-intervention, as if a state murdering citizens is less important. It does have an article about Syria where it opposes Western intervention, but neglects to mention Russian intervention. Why? Well STWC doesn't like the West very much. It would have preferred Muammar Gaddafi massacring Libyans from the air than NATO stopping that and assisting his overthrow. Why? What interests did he serve? Wasn't he waging war against his people, like he did quietly for decades by suppressing dissent? What is really telling is the STWC goes on about Western sales of arms to the Saudi and Bahrain dictatorships, but is silent about Russia and Iran's intervention in Syria. You see Russia, Iran and Syrian dictatorships are ok, or at least better than Saudi and Bahrain, and indeed far better than the US, France and the UK intervening. Its wilful blindness to what Russia and Iran does in Syria, like its wilful blindness to what Syria did in Lebanon, speaks volumes. STWC is not anti-war, it is anti-Western, anti-liberal democracy, anti-secularism, anti-freedom and anti-capitalist. It is a Marxist front organisation that provides succour for tyrannies, as long as they aren't Western backed.
Stop the War Coalition is actually "stop the war against those waging war against their own citizens". Hardly surprising, given its chairman is a friend of the Orwellian cult of dead personality regime in Pyongyang.
The arguments against Western military intervention remain compelling, and are primarily about being bogged down in a conflict where no side is an angel and there is an overwhelming risk of civil war being a sectarian battle. Yet there is a case for blocking Russian and Iranian ships from entering Syrian waters and imposing a no-fly zone. That, at least, will minimise malignant intervention on the side of Assad.
However, the so-called "peace movement" will likely oppose that, because to them peace within countries, particularly regimes that are not Western friendly and not the result of Western intervention, isn't that important. It's just another leftwing group that opposes the West that gives them the freedom and wealth to function.
There are no solutions to Syria coming from the "peace" movement or the left. The conservative right has been burned by Iraq and Afghanistan and has neither the fortitude nor the capacity to support a similar intervention in Syria. The only way Syria will get better is if Syrians will fight for freedom, if more Syrian soldiers fight against Assad than for him and if Syrian embrace values of secularism, freedom, mutual respect and tolerance for each other. The best way that can be encouraged is by hindering malignant intervention and by good people being mercenaries and supporting factions in Syria that allow people to defend themselves and fight for a free Syria.
Neither the "peace movement", nor the UN, nor the Arab League can be expected to support let alone do much for any of that.
