Listen i agree the Philipines totalling over several thousand individual island would be tough to defend, but Mac Arthur basically paniced and fled, he was and is guilty of deserting his troops when they needed him the most, and as i have said previously the veterans i have spoken too have NO RESPECT for the man. One thing MacArthur should have done is that to grow a set of balls and find a spine stay and used the 100,000 or so troops he had at his disposal and fight like hell to make conquering the Philipines as expensive in Japanese blood as possible. If you consider if for every defender to take out one Japanese soldier then that would have meant at least 100,000+ Japanese dead, very expensive indeed.
