I fail to see how the it benefits the working class conscripts to have no weapons to defend themselves with.

One last thing: NATO membership is something used by western countries to influence domestic policy in countries like Ukraine. Since Zelenskyy came to power, there's been a transformation of Ukraine to low cost labor source for the rest of Europe, causing GDP to crater and lots of people to already leave the country before the war started. This is how NATO has been since its founding. Being anti-NATO is supporting the working class.

The background issue to Crimean annexation and the war in Donbass was the trade agreement with the European Union, not NATO membership, which became impossible as the war was an on-going territorial dispute.

Though Ukrainian corruption ought not to underestimated, the decline in GDP since the beginning of Zelenskyi's term in 2019 is mostly attributable to the on-going COVID19 pandemic.
