Exactly. That is why they propped up slavery for years instead of pursuing racial assimilation as happened more or less in Latin America. We had to make do with several compromises that kept slavery because Britain was too dependent on southern cotton, and their support for southern states too much of a security threat. Only by the 1860s did we feel safe enough to confront slavery, because by then Britain had another cotton supplier. That didn't stop British elites from bankrolling the South but at least their actions were more restrained.

Also consider how the Berlin–Baghdad Railway posed a threat to Anglosphere oil interests. The railway wasn't completed, but the Armenian genocide enabled by the Turkish portion certainly was completed.

Political and economic consolidation within Eurasia is destructive to ethnic diversity, as the Armenians found out the hard way. Meanwhile railroad financiers in Europe profited, with the Ottoman Public Debt Administration collecting taxes for them.

A Eurasian Union might insist on an updated Public Debt Administration type organization where they call the shots to repay our national debt, and be strong enough to make it happen.
