Uhm, this isn't the first time Russia invaded Ukraine in the past decade. Remember when they invaded and took Crimea?
Also, they've been fucking with elections in other countries, like with Brexit and Trump. There was also the Wirecard scandal that they've been associated with. They've done massive amounts of damage internationally.
Yes, I mentioned it. That was in 2014 - 22 years after the fall of the Soviet Union.
Russia's antics have been damaging but child's play compared to the cold war. The US and the Soviet Union were engaged in proxy wars, insurgencies, coups and counter coups across the globe pretty much non-stop for nearly 50 years, all the while pointing two order-of-magnitude larger nuclear arsenals at each other.
Economic interdependence obviously didn't stop Russia from eventually going off the deep end. But it probably helped keep relations cool for quite a while.
Sure, but this is much more low level than a war. The US also messes with other countries elections & politics, including Euromaidan in Ukraine.
20 years is actually not a long time for an idea like we're talking about. This isn't human-scale stuff.
It'd obviously be a mistake to say that economic interconnectivity totally prevents war, but the fact that wars break out doesn't falsify the notion that it might make conflict less common on average. The west's relationship with Russia and China has certainly been less rocky over the past 30 years than its relationship with the Soviet Union ever was.
