I understand the idea of non-intervention. But why you protest helping Ukraine only now? Why you didn't protest when US and other nations doomed Ukraine to weak position by nuclear disarmament (in return of promises to protect it's sovereignty)? For Putin it wouldn't be that easy to continue to attack Ukraine be it still nuclear power.
And why you didn't protest when in 2014 Ukrainians suffering from ongoing invasion formed private armies which were very effective in slowing down aggression but slowly by April 2015 international pressure forced Ukraine to get rid, to reform all private troops? Ukraine now needs to protect itself only with it's somewhat outdated and corrupt bureaucratic state army.
And so little is heard to stop gun prohibitionists in Ukraine.
And you say you don't want your tax dollars being spend. But why you don't favor trade? Even Belarus, Russian friend, sells military help to Ukraine.
And why nobody count millions spent on helping Russian government here and there.
So my point being if it were already some ideal ancap world with private protection services, private armies, market opportunities to defend, with armed peaceful people and without governments being involved in almost every step of military protection then we would be able to say, Ukraine, don't seek help from our government. But did you done enough to move situation anywhere closer?
Or you think you're libertarian if you repeat what state sponsored Russia Today says?
