Tried countering this move as axis with a J1 DOW and J1&J2 Strat bomber buy (+2TT J1). Turned out the Philippines assault failed and the fighter survived to be the 4th interceptor, but I still did the strat bombing raid J3 with 3 bombers, figuring the damage I would do would hurt the Allies more than losing a bomber. Turned out all got through and shot one interceptor down, but more importantly, instead of repairing the damage, the Allies built an extra IC on West India which I could only reach from Shan State, which I hadn’t claimed yet.
4th interceptor would normally come ANZAC2 via Malaya IMO, but I think the alternate IC is a pretty radical strategy. Not sure of the advantage of it to be honest.
Certainly had trouble containing China while focusing so much on India.
