Russia wants to appear to be a world power, though I've no fucking idea why as it's a pointless and wasteful role.
To do that I suppose they decide to prop up the cheapest options out there with the most to gain from being given a hand job by them. And it annoys everyone else.
Russia does not want to seem like a world power, and it is a strong world power led by a powerful ruler. And it really annoys everyone, but they can not do anything.
Russia is still a shadow of its former self. If you compare Russia as of now and the USSR of the early 1980s, then it is clear. The USSR had a population of close to 300 million, and their armed forces were as powerful as that of the United States. Now if you look at Russia, it is having a population of only around 145 million, and the armed forces are clearly inferior to that of the Americans. That said, their resurgence after 1999, when Putin took over has been nothing short of a miracle.
Under Putin, Russia has become even worse than it was. How would Putin's propaganda did not shout about their successes really demonstrate to them no one can. Russian during this time quarreled with almost all its neighbours. Now is a potential enemy. Modern Russian weapons too, on their own can not do, and components abroad can not buy because they are under sanctions.
