The U-boats are down on the ground, so its right and proper to carry on giving them a good kicking!
Just because the current U-boat threat isn't huge doesn't mean it isn't there or cannot get greater again.
Not huge by OTL standards - by TTL standards it's probably the scariest threat out there (Obergefreiter Jones with his armoured bread van being the main other one).
Unlikely to be a Bengal famine TTL. Bengal won't be at the front line of a war zone (probably) and rice from Burma, Thailand and Indochina readily accessible and Britain will have more railway, lorry and shipping capacity available. And won't have a war to prosecute and the Imperial Japanese army and navy shooting at them which caused something of a distraction OTL
Likely to be some hunger - the harvest will still fail as OTL, and the British are unlikely to do much to help matters - but the shipping is available so enough food will come in to avoid mass starvation.
That’s like one of first air ride in central Europe in March 1939. Ine flight of Hungarian Royal Air Force hit Hungarian town instead of Slovak airport.
It's not unusual. Air navigation is hard, particularly in bad weather at night with people shooting at you.
OTL 1944/45 levels of opportunity (yay!) with OTL 1941 levels of accuracy(yikes)...
Forget Denmark, did they hit Malmo?!?
Probably not. Back when I was doing a lot of flying I remember the briefing given to someone on their first long-distance cross country flight from Cambridge to Norwich: "if you get to a large area of grey crinkly stuff, turn back because that's the North Sea". He ended up near the beach at Lowestoft. The same thing applies here - unless they somehow miss the entire Jutland peninsula, they aren't going to end up bombing Sweden. Water features - particularly the sea - are relatively easy to see from the air.
Which leads to the question, at this point, how are Thailand's relations with each of the three major powers in the area. If the British can keep the Thai neutral, India will be almost as backwater as Canada...
Also, Subhas Chandra Bose isn't going to be nearly as well known iTTL, right?
By three major powers you mean Britain, France and China, right? Not great, but that's down to history and didn't cause a war beforehand.
As for Bose, in OTL April 1941 he was in Moscow - so far I don't really see any reason for changes. Whether he moves on to Germany after that I'm really not so sure - I would suspect not. Either way he's unlikely to be much more than a footnote in history.
