What is the point of allying for free win

I'm Europe. What's the point of even playing at this point? All I would do is give Asia and Americas some enjoyment. I'd rather take the loss and move on early.

I just started sending out marines/subs into the Atlantic because I am Turkey and I just finished killing Germany.

Go tryhard mode and rape them both

Ally africa and have fun 2v2ing i guess (its in their favour kinda but still)

It depends, usually these players aren't that good and you can overcome them with skill and earn even more SP from all the fierce fighting but if you can see that there is no chance of you winning then you might as well leave. Only play games where you know you have some chance of winning otherwise it's pointless.

Ally Africa ... defend Europe (dont send subs) ... wipe Asia .. ez win
