Sources are sources, you just have to know their bias and adjust for that.
Sure, we can have different opinions but the difference seems to be between 1:1 what i claim and 2:1 what you claim. Even the best case still doesn't look good for Ukraine.
Right, just like every motivated Afghani, Iraqi, Libyan, Iranian... was worth 10 US soldiers just because they were motivated to protect their land right, solid logic! There's is your opinion and then there's what's really happening in the world. It's been years since Ukrainians were volunteering for military, Ukraine long had to resort to busification to find souls for the front lines, unsurprisingly "busified" soldiers are not very motivated and just ran away the first chance they get. Look up how much Russian soldiers get paid before talking about looting. And stop spreading fake news! You Russians are in your black hole and you won't get out of it for another 1000 years, because like your bloody brothers the Serbs, you have acquired everything you have through lies and the bloodshed of innocent people. Only fools like you and your butcher are proud of being paid to kill, destroy and steal - it's no wonder they call your army all sorts of derogatory names, you deserve it.
Just send new Russians to Ukraine, we will send Ukraine everything it needs to bring them back home in black bags, and you and yours will then falsify the data, and when the war is over, write that a few thousand Russians and a million Ukrainians died.
After 4 years of sending only enough to Ukraine for them to loose slowly, and as you claim barely enough money to pay Ukrainian soldiers just $500 per month to go against Russia, isn't it ironic to now claim that "we will send Ukraine everything it needs"? When do you think it'll happen? If i was Ukrainian I'd take it as some mean joke, like at this point 5th year into a war you surely must be just mocking Ukrainians

Seems like you have some anger issues you need to work out. Clearly you goal is just to cause as much damage to Russia as possible, regardless of the Ukrainian losses, even until the last Ukrainian, which is in line with the current EU thinking. The results should surprise no one.
Ukraine Struggles to Find More NATO Donors to Pay for US Weapons
Ukraine is struggling to secure fresh commitments from NATO allies to purchase US weapons for the war-torn country, Kyiv’s envoy to the military alliance said.
Currently, a small handful of countries are paying for the bulk of the weapons, and the UK is the only contributor that has recently joined the fold, Ukrainian NATO Ambassador Alyona Getmanchuk told Bloomberg. It’s becoming difficult for Ukraine to approach the same few countries over and over, she added.
The reluctance is compounding Ukraine’s growing financial predicament as Russia’s invasion grinds through its fifth year and peace talks stall. Hungary is separately blocking the release of a crucial €90 billion ($104 billion) European Union loan for Ukraine, and a political spat in Ukraine’s parliament is threatening to delay International Monetary Fund aid payments.
There are many more Ukrainians in EU than 1,5mil! Check your sources! Account for population on the territories now under Russia's control! And don't forget about low fertility rates during the war and excess deaths, substance abuses, suicides etc etc etc...
That's my bad, I didn't noticed that I confused things a bit. Wanted to say that there is 5-6 millions Ukrainian refugees in Europe and 1.5 million in Russia. Anyway, nobody isn't denying problems of Ukraine's demographics, it was bad already before war. But still, there is just no way that there is 50% of their population is gone.
Only Ukraine and Russia know the exact figures, but some international studies say that Ukraine lost around 140 000, while Russia lost over 300 000 soldiers.
I think even Ukraine and Russia don't know exact numbers. When it comes to front line, grey zone, it's really hard to tell these things - who was killed, who is gone, who was captured. I guess Russia will never reveal their actual numbers. Ukraine - maybe after end of war
In your estimate, how much of the Ukrainian population is gone since US brought cookies to Ukraine in 2013?
That's a misconception. Both sides know their own losses pretty well. Companies/platoons/squads all report their status daily, are monitored live, and also need to be supplied with rations and at the very least water almost continuously. Sure at any one moment the status of some units in a grey zone might be unknown but that number is minuscule less than 0,1% of the overall force. As far as knowing the losses of the other side, that's where reconnaissance and intelligence comes it. I think intelligence agencies of all countries have a pretty good estimate of losses for Ukraine and Russia. Also advancing side needs to clear out the dead, so they have better idea. After the war is over, there are lots of ways to accurate estimate census data, don't see why researches wouldn't publish it for both sides once they're allowed to.
