You begin your article with a fantasy: what if France, Britain, and the USA had provided military support to the anti-fascist side in the Spanish Civil War?

You forget what actually happened: the Soviet Union and the Communist International gave military support to the anti-fascist side while Britain and the USA did not.

But I'm glad you mentioned the Spanish War. It's directly relevant, though not in the way you think.

The conflict in Spain was triggered by the July 1936 insurrection against the country's elected government. Just as the Donbas war was triggered by the February 2014 insurrection in Kiev against the elected government of Viktor Yanukovych.

Kiev's coup d'etat was not, as you claim, a "myth".

It differed from the 1936 insurrection in Spain in that Spain's coup was a military one, whereas the February 2014 insurrection in Ukraine was a paramilitary coup.

In that respect Kiev's insurrection was more like the 1922 March on Rome by Italy's Fascisti, as political scientist Nicolai Petro pointed out at the time.
