Fun facts:
- Europe destroyed the USSR without war.
- Putin gets more resistance protests in Russia because of common sanctions
- Gazprom can't sell with profit within Russia, they need Europe
- Russia invests a lot of percentage of their GDP on military. But it's still nothing compared to Europe ( russia vs europe military spend: https://www.wolframalpha.com/input/?i=russia+vs+europe+milit... ). Remember, Europe isn't even spending 2%
- Without Ukraine, Russia can't even use their naval fleet. That's why they are being aggressive. The sanctions of being aggressive are hurting them, but cutting off oil to Europe would hurt them a lot more.
- Europe has never been so close to Moscow. They are more scared than you imagine
- Russia has way more borders to defend than any other country. That's why they are willing to get run over by China. Their relationship will fail sooner or later. China doesn't invest in Russia despite longtime promises. Their relationship will hold untill Putin realizes there is not much to gain or till China doesn't need them anymore.
Russia needs China more ( because of borders ) than the other way around. China also wants more security at it's borders, but it's less of a requirement.
- Russia's and Turkeys relationship is also not that stable. It was because of one man that they talked again, by the use of a special Turkish expression that said: sorry, but not that sorry. Their relationship could hold untill one of both actually tries to improve relations with Europe, not happening soon though.
If Europe would want to hurt Russia, they only need to heavily subsidize renewable resources, that would hurt max. 5% of Russia's GDP. No war required and don't bite the hand that feeds you ;)
