How? Ukraine would still be outside of NATO so they wouldn't gain any of that strength and the NATO members still don't want to be in a shooting war with nuclear-armed Russia - if anything, the stronger NATO is compared to Russia the more likely it is to escalate to nukes. Depending on how the money was allocated NATO still mightn't be better positioned to supply Ukraine. Like if Germany built a new munitions factory that could directly help Ukraine, if they put all that money into shipbuilding or more infantry or something it's wasted, from Ukraine's point of view.
I'm probably wasting keystrokes but
If Eurofags had been keeping up with their obligations, there would have been more available weapons to send to Ukraine. This would have a ripple effect where if Germany hadn't been allowed to keep moldering, worthless ammo on the books, their wouldn't have been a 155mm crisis early in the war. Because Germany would have been producing new 155mm to replace rotted rounds in bunkers, there might have been ammo plants supplying those orders, plants that could have been ramped up/expanded.
If the Euro defense market per-year was greater than 1 Tank and 160million Pride-flag lapel pins, there might have been some defense capacity inside Europe to actually spin-up to be able to meet the demands of actual sustained combat.
The other potential is that if Eurofags didn't scream and sob each and every time they are made to divert a single
Euro Faggot-Dollar from their "Rapefuge & Queer slushfund" to some activity that might actually result in them being able to last more than 48-hours in war, Putin may not have decided that Ukraine was worth the gamble.
In 2014, Russia were able to start (and maintain) a civil war in Ukraine as well as take territory from another country. The Eurofag response to these hostile, aggressive, and expansionist actions was to send a bunch of sternly worded letters of condemnation, put some worthless sanctions of a few people, and then buy another 6 trillion dollars of natural gas from Russia. He invaded in 2022 because he expected to have the same result this go around. If Eurofags had managed to provide even a slight impreession it was possible they weren't limpwristed sissycucks utterly dependent on Russian NG, Putin might have chosen differently.
If anything NATO countries should be moving funds out of their armed forces budgets (spending on keeping zoomers off the dole) and into their foreign aid budgets (spending on keeping Ukraine in the fight) if they don't want to put their own boots on the ground.
The usual spending-short Eurofag countries are already trying to count Ukraine spending/weapons transfers to their 2% NATO GDP minimum.
