Immature, and if what you are saying about how 90% of Vietnamese want war with Indonesia, then all of them are also immature AND stupid, and that's also the appropriate way to call your manners. Don't be that annoying Viet spiralling in delusions of themselves and others, just like a dog barking at a lion i must say. What you are saying here is all arrogance, ignorance AND delusion, stop this kind of stupidity, or you will be forever remembered as the annoying, delusional boat people who thinks anyone else "just like Cambodia", you must know your REAL capacity Viet, not your idealization of your own (L I M I T E D) power.
You and other annoying chauvinists is just like a fool deliberately stepping on a landmine to prove how macho he is, yet the fact is, he's not macho, but he's certainly stupid, and that's exactly what you are.
