If the people won't volunteer to fight, does Ukraine as we know it deserve to exist? Slavery is never justified, and that is what conscription is.
The Donbas is ethnicly and linguistically Russian. Ukraine could have let them secede peacefully. There is nothing sacred about national borders.
Ukraine could have accepted peace terms early on, but NATO intervened and said no.
The solution is not burdening every single American with debt and inflation, that's for damn sure.
South Texas is technically and linguistically Mexican.
And if they want to join Mexico, they have every natural right to secede. Hawaiians also have every right to declare independence. The rest of California has every right to break away from SoCal and form 2, 3, or more states.
There is nothing sacred about nation-states, and truth be told, I advocate secession to the individual level. Coerced association is uncivilized.
