A lot of people are missing the nuances on this entire topic. Firstly, giving Ukraine the blueprints to the missile could mean it's the export version, and that version is usually less capable than the original, always like this with military equipment. Secondly, it could signal that the UK, and possibly France working together, have come up with a new and improved version that will serve NATO better and are just getting financial and political favours for when all is done and the contracts to rebuild are awarded. Thirdly, it shouldn't escape notice that the West has supported Ukraine to diminish and weaken Russia, but also Iran at the same time, to a point that it will take them decades to rebuild to the same threat level they were before all this started... Russia just presented an opportunity but Iran was deliberate. This frees up NATO, the West in general plus its allies in Asia to concentrate on China and it's containment without any wildcard interference from other bad actors. Forthly, when Putler says the UK is now involved, then I guess it's awkward to point out that Iran, China, and North Korea are also participating in it too on Russia's side... an inconvenient truth Vlad. There is much manure being spread about all this as usual in such situations, but the main priority is to weaken Russia and Iran, and they walked right into it.
