If the West decides to supply Ukraine with everything it needs, taking one country as an example the UK, how would it do so?
I would imagine the UK doesn't have a vast munitions stockpile. Most likely it is geared up to a small, limited war of a few months, perhaps a year and then it's resupply capability is also very limited. Just enougth.
Ukraine requires millions of rounds, tens of thousands of shells. Tanks, aircraft, drones, radios, helmets you name it.
The only way I can see the UK supplying all that is to go on a war footing and turn industry over to war production.
As no country has done that exactly how will the West supply Ukraine with `every thing it needs`? Russia IS on a war footing and IS ramping up production.
Unless the West does something quickly Russia will win by sheer weight of numbers.
