[quote]Also SE Asia is just as important, afterall, if it wasn't, then Imperial Japan wouldn't have gone after it =D[/quote]

This is a fallacy. It's a circular argument.

[b]Premise[/b]: Southeast Asia Theater was important.
thus
[b]Conclusion[/b]: Imperial Japan went after it.

is the same as

[b]Premise[/b]: Imperial Japan invaded Southeast Asia.
thus
[b]Conclusion[/b]: Southeast Asia Theater must be important.

Circular reasoning doesn't work here, ma'am.
