In early 1900s would been possible a great war between British Empire and French Empire with Germany to the said of UK and USA to the side of France,or this is pure ASB ?
I have had similar thoughts along these lines.
How about this.
Tensions escalate between the US and Germany, Japan, and UK over recently captured Spanish colonies.
In 1904 the Japanese torpedo boat attack on the Russian Fleet transiting the English channel is exposed to the world when a Russian ship is struck by a torpedo. The Surviving ships retreat to a French port where the Japanese continue the attack, killing several French Civilians in the process.
Russia and France demand satisfaction that the British government cannot or will not give.
France declares war on the UK and Japan, Russian Declares war on UK.
German and Austria see there chance and declare war on Russia and France.
Italy stays neutral but is being courted by both sides.
Heavy handed RN actions against neutral American shipping causes resentment in the US.
Revolt breaks out in Ireland and is brutally put down.New American president and congress declare war on UK, Japan, Germany, and Austria.Why and howBritain had gone a very long way towards appeasing the Irish Catholic community and there was a lot less tension. If extremists try something at this point their likely to get stomped by their own community.
Irish Americans are out ranged and flexing there new political clout make war with UK an election issue, the price of their support is war the the UK.
The more extreme parts of the Irish American community are likely to cause problems if they can, but you vastly over-estimate their position. America is not going to pick a fight with its biggest trading partner and investor without a very big incentive and their no where near enough.
Italy Joins the US, French, Russian, Alliance,
Spain declares war on the US, France, and Russia, and is immediately crushed.
Turkey remains neutral.
I think the US's complete lack of interest in events outside of the Western Hemisphere is a major problem in getting the US in the war from the start. Unless someone starts sinking US ships, the US isn't joining any European war. Thats why I think it's much more likely if it starts out a a US-UK conflict and spreads to Europe afterwards.
Well, there is the Dogger Bank Incident. There are several TL's right here which propose a major European war starting from that mixup. It'd be basically Britain vs. Russia to start with, but then France might feel compelled to intervene on Russia's side, which might trigger German intervention. Not sure how Austria-Hungary and Italy would react at that point. This is before Bosnian annexation, so that particular Austro-Serbian flashpoint isn't there.
