Before World War II, the Philippines was occupied by the United States and reduced to a colonial possession, vastly different from the Philippines of today. If the Philippines insists on providing the United States with a war theater, it would have to place its mountainous secret passages near Taiwan, air-raid shelters, ports, urban expressways, streets, and subways under American control—effectively transforming itself into a semi-colony.
Philippines were getting independence riiight before 12.1941.
This was one of the reasons how they managed to get it in a worst way possible - american actions and reinforcement of Philippines assured japanese, that under all circumstances country must be neutralized(occupied), because it will provide every possible assistance to US in case of war, and US won't be asking anyway.
Which they didn't, since september 1941 all doubts were thrown away, and US plan was, again, to save Philippines in case of war (i.e., despite of what some people say, w/o Pearl Harbor americans would've rushed battlefleet there after all). Newly elected(november 11) Quezon specifically approved this.
At the same time, Quezon opened negotiations with Japanese and tried to keep his country neutral and away from incoming storm.
McArthur - acting in his typical fashion very much on his own, and driven by local friendly relationship and possibly quite geniune attempt to give Philippines a chance(meaning, sticking it to Washington), - tried to give breathing space to Quezon, and because of that fortification/reinforcement of Philippines was seriously sabotaged throughout 1941, up till the last moment - even in the morning of dec.7 1941 there is very serious suspicion that this was the true reason why McArthur hesitated to send in his bomber force, and not cartoon villain stories. He was quite close to being a cartoon villain, but not in this particular way.
But sent he did, and these hundreds of aircraft were there in the first place.
At the same time, in november 1941 and under absolute secrecy, US navy prepared some schooners with Philippino crews(quite happy to be enlisted in US navy...without knowing just what for) to send them in path of Japanese troop convoys, to get them conveniently sunk and get a solid casus belli. In a true colonial fashion, there were no americans on these prepared boats. Not like, as we know, Japanese needed any invitation to invade, but still, it's a rather ugly page of history.
I.e. everyone in this story negotiated in absolute bad faith (Roosvelt&chiefs of staff, McArthur, Japanese, Quezon), but Philippines had a say - and their say was half-assed agreement with being US base. Just without taking responsibility for that.
All of this, of course, is pure history. If it remind you of something - well, conclusions are yours.
