The whole UK and France wanting to send their forces into Ukraine to fight Russia confuses me.
If they go ahead and do this I have a few ideas for outcomes:
1. They send in a large "advisor" force (apart from the ones there already). These advisors are there to help "advise", but they go into combat and eventually get withered out (fighting is similar to trench warfare with drones and such, against an experienced and combat hardened force backed by a large country, not a bunch of rag tag sandniggers - who BTFO'd them too). They might bitch and moan about article 5 meme, but since they're advisors... well it's not technically war or whatever.
2. They send in troops to join the war effort. The troops get wiped out faster, probably due to them going into action sooner (perhaps some refuse and/or go AWOL); they'd probably scream about article 5, but I doubt The USA would want to get involved under The Trump admin (apart from some rouge glowies).
3. They continue to bitch and moan (hopefully this outcome, as it's not sacrificing more of your men for the meatgrinder).
