I know many so called military analysts have said the war is slow going and Russia should have taken the country by now. However people are quick to forget Russia isn't just fighting Ukraine had Russia been fighting Ukraine alone without support the war would be over years ago. Ukraine has multiple sources of support, mercenaries, NATO intelligence, NATO personnel within the country in support and advisory roles, huge financial support, and huge amounts equipment, munitions, and fuel, they also get support from western charities. Russia on the other hand had some support from China, Iran, North korea but nothing on the scale of what Ukraine has had from the west, and it hasn't been free handouts either but rather trade deals, no charities helping, a very small mercenary/volunteer element, zero financial support, and faced the biggest sanctions package theveirkd had ever seen, yet thry have managed to keep going, the economy is surving, and arms production is higher than nato combined, while Ukraines economy and military production is almost at a standstill. And the west are still buying russian oil and gas through the back door, Ukraine is facing a naval blockade, a huge energy crisis, and have total disregard for it's population and troops. Russia as Gazza mentioned is playing the attrition game, this is a normal tactic and reduces your casualties it's not something new. Taking land comes when the situation is favourable hence the slower speed. And let's not forget Ukraine had years and years to plan, prepare defences in the Donbass and other areas, that's not something anyone is going to be foolish enough to run into head long into without mass casualties. Russia has also developed various military systems during the war and still fulfilled foreign orders, just recently delivered a squadron of Su-35 to Ethiopia a year ahead of schedule. Yet the western media keeps telling us Russian military production is in a terrible state. The fact that Russia is firing off missiles and drones in huge quantities on a daily basis tells you something, and tanks, aircraft, and munitions are still being delivered is another good sign things aren't as bad as the west make out.
