What if Japan attacked British, French, and Dutch possessions in South-East Asia and the Pacific without attacking the Phillipines or Pearl Harbor? What would the American response be? How would this affect the course of the war in general?

If you use the search facility, although it can be a bit awkward, you will find this comes up fairly regularly.
The key point would be whether America was able to join the conflict fairly immediately. Personally I expect not although some would disagree. If they don't then Japan has a very good time until either they totally over-stretch themselves or the US does come out of neutrality. In the latter case, if the Philippines have been properly built up things can get very bad for the Japanese. However if Britain is forced to make peace before that point it could get even nastier in E Asia.
If the US does declare war on Japan almost straight away a lot would depend on what plans both sides have and how they work out. If they have left a little back in terms of forces the Japanese could still attack the Philippines almost immediately after the US dow and that could potentially be nasty for the US. A politically inspired mission to relieve the islands could see a disaster markedly worse than Pearl Harbor. If their really lucky, after a dow that has split opinion in the US, that might mean a peace proposal being accepted. [Although that's fairly unlikely]. If no such early US disaster, but they still lose the Philippines the US will win in the end, as they have too huge an advantage in terms of production, but could be a bit longer and bloodier.
