Ukraine soldiers are trained for 3 months. There can't be much infrastructure needed for an attack since the battle is on enemy territory when it starts.
Dude. Stop. You don't know what you're talking about, and every addition is making it more cringe.
I have the training to train basic jaegers in two weeks. Those are the simple infantry for the front. More specialised soldiers, like NCO's, especially specialist NCO's like me, take far longer to train. You know in strategy games it takes longer and costs more to churn our specialised soldiers?
Imagine that you have a league of legends/starcraft/CIV game going and at more than halfway through you decide to just sell all your units and pivot entirely? How would that ever make sense in any game, if not as some weird YouTube challenge? No actual pro-player would ever try something as silly.
That's a rhetorical example that I hope will convey some of what I'm trying to communicate, since you don't seem to understand how complex military strategy on a national level is. It's not like a sentence or two. It's systems upon systems relying on other systems which are regulated by resources or practical necessities, leaning on other things which are dictated by something else entirely etc etc.
Iraq, Libya and others. At worst we call it a special military operation in support of Ukraine.
So you're genuinely advocating breaking international law? You don't actually care about morals? That's... off-putting, to say the least.
"After these comments..."
Was it you who commented earlier in the thread about something something "fantasy, not reality"? Because you live in some weird warmongering fantasy war fetish laa-laa land. There's no fucking NSA looking at what people have been writing if you're conscripted to be infantry. You're taught how to march, then how to obey, then given a gun, taught how to shoot it, then how to shoot it while moving forward, then taught how to move forwards while shooting it under enemy fire, then how to move while shooting while under enemy fire and communicating with your group (or listening to your group leader/fighting pair).
So, which country is it then? Because you're saying "we will attack..." but see if there was an offensive from Europe to Russia, it's highly likely I would be fighting, but I suspect you wouldn't.
So perhaps stop it with the childish warmongering.
Edit and yes, there is a need to wait for Ukraine EU membership, which there's attempts to rush through, but international politics don't work as willy-nilly as online forums. You can't pretend to ignore global geopolitics.
