@crest the only ones that can truly say if attacking energy systems versus oil industries is the better route remains between the combatants I'd guess. I certainly understand the strategy each is employing, regards energy/oil systems. As to winning fast enough or altering the wars trajectory, after 4 years Ukraine still keeps hanging around so they have hope at least.
There is no doubt some truth to that but that doesn't mean objective analysis of known information isn't a good predictor of results. Unknown information is always a possibility but it's not exactly a hard barrier given the amount of information that is available. And yeah Ukraine is hitting way above the belt here, I don't think anyone it even the Russians dispute that, and that's taking into account Russian incompetentance early on.
The question that is relivent here isn't about how well Ukraine has done vs a much larger and objectively competent adversary those accolades have been earned regardless of how this ends. It's a question of how long they can continue to fight and at this point There is also a legitimate question as to the will to continue fighting. As in the national will not just leadership or individual units. I know your passion this issue so don't take that as a insult to the Ukrainian armed forces or population it's not if anything it's a compliment. But one would be wrong to not acknowledge what many in Ukraine do that the of consequences of continued fighting are not worth the cost to the nation. And the price of peace goes up the longer the war continues.
The message i gather from alot of sources is that the general opinion is without outside manpower and continued Infact increased military and economic support there is no win option. Or at least it is a meaningfully large enough opinion that a strait up military to military victory over Russia is unlikely to occur.
There is a question to be asked about Ukrainians willingness to fight with allied reinforcement but there is little prospect for a strengthening of the Ukrainian army from this point, Infact objectively it is lossing co,bat power at a faster pace then it can replace it. In terms of both quantity and quality tho again that could change with outside support
In short Ukraine may still be willing to fight for years but there not willing to fight alone for that much longer At least not as a traditional military force. Unfortunately it's fairly clear that isn't coming
