There is no development strategy for Donbas in Ukraine except to take billions from Russia. In Ukraine, even next year’s budget does not include funds for the Donbas. They are not going to reintegrate with anyone.
Bolivia and Venezuela are similar in their independent approach to following a socialist path to break away from the hegemonic interference and economic exploitation of the US and its allies. Both countries have been successful in reducing poverty and achieving economic growth by the social use of their resources. And both countries have been subjected to a US-promoted hybrid war for regime change from a socialist government to a more neoliberal pro-US government.
Conspiracy theory. No evidence is provided to support the claim. This is part of a recurrent disinformation narrative about US-led regime change operations against left wing governments in Latin America. You can see other examples of this, such as the alleged presence of a US marine in the Venezuelan barricades and the promotion of a Ukraine-style 'colour revolution', the training of Venezuelan exiles in Guyana for military operations inside the country, preparations for a military intervention after forcing Brazil to join NATO, deliberate blackouts in South America caused by the US, or the existence of plans for the secession of oil-rich regions in both Venezuela and Mexico. Also falls within the broader pro-Kremlin disinformation narrative attempting to deny the existence of genuine grass-root protests, portraying them as foreign-led efforts and fake colour revolutions.
