So threatening to not interfere with genociding the people of Ukraine is not worth starting a war over.
Ceteram censeo Putinist Russia esse delendam
I dunno man. The whole reason the UN was formed after WW2 was to prevent shite like that from ever happening again.
What is the UK supposed to do? Start sending missiles over moscow? Wars should be a matter of last resort, and when you embark upon war, you should do so prepared and with a clear win state in mind. The last time the UK engaged its forces in an ill-thought out Crimean intervention, it bled the lives of many of its men to achieve a settlement it could have already achieved through politics. All in all the UK's response has been admirable; we were training Ukrainian regulars in NATO style warfare even before the Americans were, and for all of Boris Johnson's many failings, his consistent support for Ukraine was commendable; Zelensky even saying he felt
the UK was amongst Ukraine's allies as one of the only interested in actually helping Ukraine win, rather than just bleed the Russians. (The Polish are interested in both). Assassinations and use of chemical weapons is haram, but is best met with a proportional response - unequivocal support of Ukraine, sanctions and so on. You also have to be careful with how you respond to such skulduggery, else you'd also have to declare war on states like Israel for using British passports to carry out assassinations or coerce british MPs. Proportional responses. On the practical side of things, the UK armed forces are still very much geared for expeditionary conflict, and is not really prepared for a sustained continental European campaign - our MPs have for years been talking about how "
a tank battle in Europe is not possible" and as such have been cutting all the personnel and equipment you would need to prosecute a continental European campaign. We have pretty ships that lack sufficient weapons engineers. We have fine aircraft that lack reserve pilots. We have elite light infantry brigades without sufficient transport options, and almost every single one of our infantry brigades are under strength. Our challenger 2 tank fleet is being halved, and even if we wanted to order new challenger 2s, they're no longer in production. The successor tank system Ajax is looking like it will be scrapped altogether. Couple that with the fact that any naval intervention in the black sea has to come through the bosphorous with Turkiye's permission... And with the Russians knowing exactly where your ships are, which is a prime missile attracting option, there are limited options for the UK military to directly attack Russia's heartlands in any strategic sense that doesn't escalate into nuclear war.
