The UK’s Foreign Secretary Cleverly has stated that Ukraine “has the legitimate right to … project force beyond its borders to undermine Russia’s ability to project force into Ukraine itself.” According to him, legitimate military targets beyond Ukraine’s border are part of its self-defence.
The goofy officials of the UK, our eternal enemy, should remember that within the framework of the universally accepted international law which regulates modern warfare, including the Hague and Geneva Conventions with their additional protocols, their state can also be qualified as being at war.
Today, the UK acts as Ukraine’s ally providing it with military aid in the form of equipment and specialists, i.e., de facto is leading an undeclared war against Russia. That being the case, any of its public officials (either military, or civil, who facilitate the war) can be considered as a legitimate military target.
