Short answer: yes. Longer answer: there is always an unbelievable amount of EU and NATO fuckery going on in Serbia, has been going on for years if not decades at this point. The government is already semi-comprador and basically capitulates to the West on every issue that matters.
But that's still not enough for the imperialists. They have to stamp out even the token lip service that the Serbian government offers to Serbia's historic affinity with Russia, which they only do to placate their generally russophile population. Much the same as how Turkey pays lip service to Palestine because their population is largely anti-Zionist but behind the scenes they are aiding and abetting the genocide.
That is how insecure the Anglo-European elites are and how desperate they are for total control in Europe. It's the modern incarnation of the Nazi concept of "Gleichschaltung". Same reason they are constantly trying to take down Orban in Hungary (who is a piece of shit for a multitude of different reasons...anti-communist, islamophobe, Zionist...all usually a plus with the EU elite, but again, nothing but total compliance and absolute alignment with everything Brussels says will satisfy the Euro-Atlanticists) and why they tried to assassinate Fico in Slovakia.
Neither of which are really a threat to the EU or NATO in any way, but they still pursue too much of an independent policy so they have to be taken out. Serbia is a microcosm of that same phenomenon. It has a weak government and a very unstable socio-economic situation, so they do 99% of everything the EU and NATO demand, but the EU and NATO won't tolerate anything less than 100%.
At this point there is a fanatical obsession in the European elite with the idea of uniting all of Europe under the Brussels diktat (just like the Nazis dreamed of uniting all of Europe under their banner...it's no coincidence that many of the Eurocrat elites have Nazi ancestry), establishing complete ideological and systemic uniformity across Europe, and ideally propagandizing every single European into hating Russia. They are investing a huge amount of effort into squashing any and all dissent no matter how small. The more cracks that appear in NATO and the EU the more desperate they are to accelerate EU and NATO expansion, believing that if they manage to pull every single country in Europe into these organizations that this will solve or postpone their problems.
And yes there is also a material motivation to this because this is how they justify pumping more billions of Euros into the military, which is a huge opportunity for most of these elites to get very wealthy, but a significant number of these people are really ideological true believers. Their fanaticism should not be underestimated.
