Well Grey, I'm almost sure some Australians (though maybe not New Zealanders) were involved in the Boer War. All the dominions at this point in time still regard themselves as "British" rather than distinctly "Canadian" or "Australian" or "New Zealander" (only South Africa being an exception where the local whites regard themselves as either "Boer" or "British"). Australia and New Zealand were involved in WWI even though that war started out as a European war and after the quick campaigns in the Pacific they sent soldiers to Europe. That was because they wanted to, out of a sense of being loyal and "British" so when the UK goes to war, they go too. Same applies here. I don't think I made Portuguese Timor a price of British intervention, insofar as the Portuguese would still rule it, but I suspect Australian influence in the half-island colony will be extremely strong after 1911.
"Regarding Spain, Amedeo died in 1890 but his son, Emanuele Filiberto, the Duke of Aosta is alive and well, and IIRC often viewed himself as SUPERIOR to the King of Italy. He could well lead a strong faction in favour of intervention in Spain, with personal ambitions to reclaim his family's 'right' to the kingship, but more openly stating that Italy's national interests are at stake."
So we would have an Italian duke claiming the throne of Spain...would this bring about a de facto Italo-Spanish union kingdom? Also this would mean Italian involvement in Spain and war against Turkey...
Well, Portugal is going to be better off and stronger, not materially (at least not yet), but institutionally, as from 1911 there is now very little chance of potentially destabilizing coups and counter-coups and there will not be 46 governments in 16 years as Timestorm stated happened in OTL (that gives a rate of 2.87 or basically 3 governments per year- now that's unstable any way you slice it). I would wager on Portugal having now at most 8 governments or maybe even 4 or 6 in the next 15-16 years.
Surely Portugal is now devastated and I would wager that it would not recover to pre-war levels before 1913 at earliest, but the British now have a small stake in Portugal and have earned preferential trading rights with the Portuguese empire (which still has lots of valuable raw materials such as diamonds, sugar, etc.) and can now establish bases in Portuguese territory (so the Aussies can set up shop across the sea in Portuguese Timor and the British can set up bases in Portugal, the Azores, Madeira, and the colonies that in OTL became Angola, Mozambique and Guinea-Bissau.
As you said earlier, the Portuguese contribution to any WWI (which now seems less likely to occur in 1914 like it did in OTL as you said, but maybe in 1911) will probably be more of a strain on Britain than any help, but Portugal will probably not require direct British support to transport their soldiers as they would have borrowed, bought for cheap or maybe bought at standard price, old Royal Navy and Marine Nationale (French) transports, cruisers and battleships. The Portuguese will probably also now buy the new British and French weapons that have developed as a result of this war, so Britain will not need to exhaust herself too much in equipping the Portuguese Army (which is now experienced).
The Portuguese contribution will probably not be as good as I imagined, but it would probably be better than you stated for OTL Portugal (which is now different).
"I think your idea that Morocco will blow up greater is probably the way to go. There's a Spanish Civil War on, with Italy and Britain involved, presumably some degree of French involvement too. It will look to Germany like they can push and push and get their way, and don't forget this is only a couple of years after Russia backed down after Austria-Hungary's annexation of Bosnia-Hercegovina. Germany could well look on this and risk war...and get it, much to their surprise !"
Could do yes, only thing is I need to find out when the Moroccan crisis erupted in OTL.
Hmm..I wonder how a 1911 Franco-German war would play out? Isn't Schlieffen still alive? If Germany invades through Belgium then Britain may get involved as in OTL. But I am not sure if Russia will get involved (although it is probable). Austria-Hungary will probably side with Germany, but oddly enough Serbia may escape the flames as A-H has no real beef with it for now. The Balkans may be oddly peaceful, or the OTL states of the Balkan League may take this opportunity to beat up on Turkey as a separate war from the Moroccan Crisis one (or maybe the Balkan League, containing a number of Russian proteges will join the Allies).
