Countries will support the likely winner, or more specifically, whichever choice is advantageous to their national interests. When Turkey's coup took place, for example, Western countries absolutely wanted Erdogan gone and Ataturk's values restored. It wasn't until the coup had clearly failed that the vast majority of countries expressed support for Erdogan and his regime. Who supports who doesn't confer any moral validity to a people's right to democracy and independence, though I understand if you mean the practical advantages of support. Either way, we may quickly see these international attitudes change as events progress, especially if Spain takes away autonomy in Catalonia.
