If you think about it - it's not our countries, it's only the USA/west . We(Russia) had friendly regimes in and around the region in Lybia, Iraq, Iran, Egypt, Syria, Ukraine, Georgia for years after USSR was dismantled.
USA instigated bloody revolutions and if unsuccessful they waged war against those countries, killing their leaders and supporting terrorist groups activity there.
You're right in some regards, but wrong in others. Let me give you the recent history of what happened.
Back in 2010 a Tunisian street merchant by the name of Mohamed Bouazizi had his goods taken from him by the authorities, was slapped, spat in the face, and left in the street with nothing. Apparently this sort of thing tended to be the way the authories had been conducting themselves towards Mr Bouazizi for years, and he'd had enough. He set himself on fire in public. This captured the imagination of the Tunisian people who had, for years, been getting sick of Ben Ali government (which tended to get around 90% of the vote in Tunisian "elections"), and thus he became a symbol of someone willing to fight against the oppression of the corrupt institution of the government. A revolt occured as the Tunisians rebelled.
The rebellion against dictatorships spread from Tunisia as popular uprisings occurred across the Middle East and North Africa, in what would later be called the "Arab Spring". An attempt, by the people, to overthrow oppressive and tyrannical governments. In some cases (like Egypt) these uprisings were looked at with some resentment by the West because Western governments had spent a lot of time and resources propping up these dictators. In other cases (Syria) the Western governments responded with glee because they saw yet another opportunity to expand their powerbase in the region.
Syria became the biggest point of contention. Assad had absolutely no intention of going, and would stop the revolt in its tracks, or so he thought. With the exception Saudi Arabian leadership Assad is probably the worst the Middle East has to offer in terms of a willingness to destroy human life to keep power. He launched an absolutely brutal crackdown on protesters and anyone who was even suspected of having sympathies with the Arab spring. Thousands were killed and Sarin gas was used on ordinary people (
Scishow episode on Sarin). This gave the West what they thought was a good excuse to move in and remove something that had been an obstacle to Western dominance in the region for decades.
Much of the Arab spring in Syria had fled or gone quiet, but some of the more militant types decided to take up arms. However the diverse ethnic makeup of the region meant there were (and still are) many different factions with many different ideas of what Syria should ultimately be. The USA, as usual in these situations, completely failed to understand this and started arming anyone at all who they thought might fight Assad (except, notably, the PKK). Among these groups was ISIS (the history of which goes back years, to before the invasion of Iraq), which was actually the same group who had been fighting the Americans in Iraq for years (fun factoid: Al-Zarqawi founded ISIS), as well as the FSA, STA,
Jabhat Ansar al-Islam etc (the list is
absolutely massive, and the only faction not receiving outside support is ISIS, odd how they're doing so well).
Assad was no longer just cracking down on protesters but instead had a bloody revolution on his hands, putting his army up against battle-hardened militias, many of whom had experience fighting the Americans in Iraq, and who now had, ironically, been armed by the same Americans. In a panic he turned to others for help.
Russia, determined to see their base in the Middle East (as well as their eyes and ears) remain safe, supplied him with weapons and equipment to fight back. This led to an escalation of the conflict as the USA decided to bomb certain targets to aid the rebels/terrorists in Syria. More weapons, munitions, and hardware ended up being delivered to all factions involved in the conflict as the stakes grew higher and higher.
So what started as a protest march degenerated into all out civil war with some of the most deadly and technologically advanced weaponry the world as ever seen. Roads, bridges, rail, power, gas, and water all became luxuries. Life was unlivable for most of Syrias millions of ordinary people. The statistics on this boggle the mind. 250,000 people kiled, less than half the population still live in the home they were in before the war started, and 4 million Syrians have fled the country entirely. The refugee crisis started as people tried to escape the fighting.
The refugee crisis, and the rather cowardly and inhuman response from it by both the East and West, is another topic entirely. But the general point is that what has happend has been the fault of almost
everyone.
Russia is to blame for propping up the Assad government.
Assad is to blame for being such a terrible excuse for a human being.
Obama, Cameron, Bush, Blair etc are all to blame for playing their stupid game of Risk with the lives of people in other countries.
I personally am to blame because I haven't (so far) gone into the center of London and stood on the street, stopping traffic, refusing to move until our government stop being imperialist sociopaths, stop supplying people with weapons, and instead let refugees in and give them shelter and safety.
You are to blame for not doing likewise on the streets of Moscow.
In fact the only people who are not to blame are the ones who were just trying to live their lives in Syria, who found themselves at the center of a war they didn't start, which they didn't want, and which isn't even about them. This entire thing brings me to tears.
The only aggressor and killer through these last 30 years was and is USA. Russia just can't back down, because otherwise we'll be annihilated
Russia has bloody hands in this too. While the Ukrainian power-grab by the USA was foolish Putins support for the Assad government has been unforgivable. What you should remember is that what Russia is doing is purely being done for Putin and his need for power - specifically to keep the Russian airbases and their naval base in Syria in allied hands. I actually believe that Putin cares about Russia and Russias people, but only because he considers them "his".
I understand your pride, and I understand how you must dislike the West right now. I myself am completely ashamed of much of what I see my government doing, not to mention the absurd rants and horrific ignorance some of my countrymen are giving on the situation. But that is all a part of the problem. But the only way this will get any better is if we stop with the "us and them" mentality. The entire concept of nationality and nation states, tribes, factions, is a major root cause of this.
We're all people, and we should try to do our best for other people, no matter where they come from, what the colour of their skin is, the name they give to their God (or the lack thereof), or whatever languages they speak. It is the only way out of this that doesn't involve genocide.
