Who We Are Arming In Ukraine

I don't know how supplying Ukraine with weapons to fight Russia with is not an act of war, it seems that if it isnt a British person in the tank or firing the weapon it doesn't count as us being involved but we are sending £100 million worth of rockets, guns and artillery to Ukraine to aid them in their fight against Putin's invading hordes.
As we have seen many times before, the problem with supplying weapons to a nation is that those same weapons can easily be turned against us as we found out with the Taliban who benefited from a decade of us shoving weapons at them only to see them forcibly shove them back at us when we fell out.  
The US Government estimated that between 2003 and 2016, the US unloaded 358,530 rifles, 64,000 machine guns, 25,327 grenade launchers and 22,174 Humvees to the Afghan forces it fought alongside, much of which ended up in the hands of the Taliban and ISIS which they used to bring such ruin to Iraq and Syria.
Obviously Ukraine is different to Iraq, Syria and Afghanistan but there is evidence that one of the recipients of our military hardware is units like the card carrying Neo-nazi white supremacists Azov Battalion and Social National Assembly who said their mission statement is to: 'lead the white races of the world in a final crusade against Semite-led inferior races'.
Pre invasion, they were vilified for physically assaulting migrants, gypsies, the LGBTQ community and anyone who opposed their nationalist views and a report by the United Nations Office of the High Commissioner for Human Rights (OCHA) accused the Azov regiment of violating international humanitarian law but despite that they were drafted into the national Army to repel the Russian invaders although they were asked to remove the Nazi symbols such as the swastika and SS regalia from their uniforms.
The question to ask is when the war ends, and we all hope that will be soon, what happens to those powerful weapons which we have poured into a war-zone and is now in the hands of far right Nazi sympathisers?
Unfortunately, we have recent history to look at to see the horrendous answer to that question.
