Their treatment of all their neighbors show that they don't deserve any voice in international affairs. Their methods of gaining influence are to just start a separatist movement in a neighboring country, start a war there, and then intervene in the name of "protecting their people".
This is exactly what the US military is falsely accused of constantly. So no, their interests are irrelevant.
Falsely? We trained, armed, and funded the creation of ISIS to fight Assad, drawing us into a third war in Iraq when ISIS went rogue. We provided air support to extremists who overthrew the government and turned it into a failed state. We funded and armed the Taliban in Afghanistan to fight the Russians during the cold war, leaving their country tattered. We puppeted Iran into an Islamic revolution. These aren't false accusations, and neither is it to say that the US manipulated the overthrow of Ukraine's government, and then openly invited them into NATO prompting the Russian invasion, which we followed up with openly expressing our intent to bleed Russia dry.
