That's not surprising is it sir? You can't escape from Russia invading a sovereign state, encouraging insurgents in Luhansk and Donestk, when it's far from clear a majority wish to join Russia or even be part of an independent republic, not forgetting the annexation of Crimea. I'm sure British exporters would favour a more cordial relationship, but there have been incidents too numerous to mention in recent years to normalize relations.
NATO has intervened in the affairs of sovereign states and the United States has invaded sovereign states - including Iraq and Afghanistan, and intervened in Libya and Syria. I assume you condemn those actions too? Or are you arguing not for an international order but purely for the self-interest of the United States? Perhaps you could clarify. I believe Britain's national interests are in neutrality outside NATO and amity with Russia.
I am not taking sides. Neutrality means neutrality. I have no idea if the Russians are right or the Ukrainians. The Russians claim that ethnic Russians in eastern Ukraine are persecuted by the government in Kiev. The US-NATO-EU media hegemon claims that Putin is invading a sovereign state and screams that he is a murderous dictator, but that is not how it looks from a Russian perspective. From the Russian point-of-view, The Ukraine is part of the Russian homeland and a keystone of its revanchist claims (in point of fact, the Ukraine rests at the core of the historic Russian nation and Kiev is Russia's ancient capital, not Moscow). My point is that it is complex. Roughly half of geographical Ukraine has a large ethnic Russian population, and they form a majority in some areas.
Then there is the geopolitical aspect. In the wake of the fall of the USSR, the Russian Federation received solemn assurances that NATO's ambitions would not extend into the East and threaten Russia strategically. NATO - in effect, the United States - has gone back on this assurance and pursued an expansionist policy. Russia has a right to defend itself.
That is a summary of the other side. I could say more. None of it is to say Russia is right, but it is not a simple matter and I think the characterisation of Western politicians as foolish and ignorant is not far off the mark. Britain's politicians should be pursuing the national interests of Britain, not the agenda of the Washington Beltway (and it is highly debatable whether that is even truly in the interests of the United States).
I also see you mention nothing about the outrageous interference in personal liberties and property rights of Russian nationals in the West, indeed the commercial and economic attacks on Russia itself by supposedly privately-owned businesses.
