can german and portugal unite with POD before Franz ferdinand assanination
and after 1900?
and after 1900?
It will take several but:
The Russians crush the Japanese in quick order
They therefore keep to the Bjorko alliance with Germany smashing the Entente as France has no choice to adhere to it rather than to Britain
Then in 1910, when Revolution breaks out in Portugal, the Russians and the Germans seize upon it as an opportunity for gain and move to restore order in Lisbon. Britain is helpless and can't intervene as the French (most reluctantly) and the Spanish (who want to defend the monarchal principle) allow the Russians and the Germans to send forces by rail.
Having restored order in Portugal, the Russo-German alliance turns their attention to Persia where the Russians pour forces in to destroy the Parliamentary forces.
Afterwards, the Russo-Germans strike a deal where by Germany gets a mandate to occupy Portugal and her colonies and Russia occupies Afghanistan and Persia
