This is already a proxy war. For one thing calling this a full NATO vs Russia war is misleading, but on other hand calling those non Ukrainian fighting in this war on Ukraine side as 'pure' freedom fighters is also not reflecting on reality. The war will be over by now if West not pumping resources including money, assets, Intel and 'contractors' to 'supplied' Ukrainian.
NATO help not only giving armament and training to Ukrainian, but also provide venue for some 'contractors' to operate in Ukraine. Some training on Ukrainian themselves will not be enough to operate those assets given to Ukraine, by themselves. There're videos or article granted from Pro Russian telegrams, but coming from Ukrainian soldiers that talk about Polish 'contractors' that operating Poland supplies Krab SPGH for example.
Westerners media claiming foreigners fight on Russian side as 'mercenaries' while foreigners fighting on Ukrainian side as 'freedom fighters'. Come on, things are not white and black in this war, and there're many 'grays' on both sides.
In reality both sides claiming foreigners fighting in their sides as 'freedom fighters' and they're coming 'purely' on their desire to fight as volunteer. Well again both sides full of crap on this matter.
