There's no need for WW3, when you can fight it on a proxy basis !
We'll back the Ukrainian government and Russia will back the 'ethnic insurgents' , militia, or whatever they call themselves. Then each side can sit back and claim the moral high ground. We are supporting a 'legitimate, sovereign government' and the Russians are defending a 'persecuted minority' (for once !). Much easier, cheaper and safer to get someone else to do your fighting for you. Parliaments are reluctant to involve their own troops (thanks to Tony B-Liar), but much more willing to equip someone else's !
