It is actually pretty simple unless you are a bot, of course. The vikings didn't annex russia, they have merely replaced the rulers with one of theirs, keeping the rest as it was.
The mongol conquest also hasn't been an annexation. It was more like a racket, with the russian princes paying protection money while being free to launch wars of conquest on their own. Pretty common in history, really. See danegeld as an another example.

At the same time when vikings conquered parts of it and at the same time when the mongols conquered parts of it. And obviously after that, too. So yes, "throughout the history" is pretty much correct.

How do you think russia got so huge and multi-ethnic? Pure conquest.

Garin's beam was not infrared, it was visible light created by some kind of chemical candles IIRC.

Biden was not worse. He did not allow to strike deeper than 300 km into russia with american weapons, that's all. The ban is still in place, domestic weapons are used for deeper strikes. Also forbiding donating jets, helicopters and tanks is bullshit, Ukraine received all of these while Biden was still president. Trump, on the other hand, blocks weapons and ammunition, even though the EU has paid for them. The orange shitgibbon is putler's tool.

In WW1 the aggressor lost.

The laws of thermodynamics.

Autonomous forklifts have been a thing in factories for quite a while now. The AI driven stuff is being added to save money on sensors.

Look closer. It is not "a bit sexist", it is full blown incel shit.

And that's nothing compared to his dad. That dude is guilty of a number of genocides, and his temper tantrums and logic put Lord Emperor Trump to shame. Like, punishing his pet nation for its leader conducting a census that the god himself ordered in the first place.

Maybe they are. The again, maybe you are. Have you considered that possibility as well?

Yep, my printer is of mostly my own design, somewhat inspired by the LH stinger.

Insufficient training is also one of the reasons. In Berlin, even the beat cop training takes 30 months. LAPD academy trains their recruits for 6 months.

I see. My klipper host is a repurposed thin client (Dell Wyse 3040) which is way overpowered for the task.
