It's both.

On the one hand it's the leadership's ineptitude and corruption making them fail at a lot of stuff.
On the other hand it's the total disregard for their own people's lives (and the sheer numbers) making them dangerous.

On one side, this toddler can't lift more than 5 lbs and can't manage its hands or feet.

On the other side, this toddler is the greatest threat to any pet it can get its hands on.

Russia can't even invade it's neighboring country without pulling out mothballed tanks from the 70's, and is being stopped by hand me down gear that is basically cold war era equipment.

Russia is also the greatest threat to Europe because they have actively said they want more territory, and are literally committing acts of war against countries in Europe all the time. Ergo, they're the greatest threat to Europe right now.

It's really not that difficult.
