Despite claims from the US military industrial complex looking for more money, China, NK, and Iran can not do much outside their own borders. Russia is doing a poor job and it is much stronger than the other 3. Only the US maintains the ability to invade countries around the world. UK would be #2.
The UK (and France) were pretty lame in the Libya war, if I'm not mistaken they had to resort to getting help from the Americans when it came to re-fueling their planes mid-air. I'm too lazy to search for links for that, to be honest.
Also seem to remember some scandal with some RAF pilots getting very shitty food at an airbase in Cyprus during the Iraq (or Afghan?) war. That one is more fuzzy for me, though, and maybe it's not even that important, as in shitty food in the military might be a fact of life.
Later edit: I did search for that Cyprus thing, turns out it was more recent, from 2014, since the West was bombing ISIS [1]:
> Raids against Islamic State are being conducted from RAF Akrotiri in Cyprus "with broken jets and tired and fed-up people", BBC Newsnight has been told.
and
> In a letter, a serviceman said the base was being neglected, morale was poor and ground crews had taken to eating humanitarian rations meant for Iraqis.
Having to take food from "humanitarian rations meant for Iraqis." doesn't sound ideal to me.
China is interested in weak Russia so that they can take its territory. They only support Russian aggression against Ukraine to benefit from the Russian isolation economically, wound Russian army, economy, and slowly digest it. Even when Soviet Union existed, they were on bad terms with Chinese Communist Party. Even Chinese hate Russian nazis.
Edit: Out of ~90 something joint non-binding agreements between China and Russia, only 4 were actually acted upon by Chinese government.
Digestion of the economy already started, among other things Russia has joined Union Pay, Chinese payment processor.
