2 most commonly accepted death are either poison from his general (antipater) or malaria fever contracted at india. I think the question should be HOW he died.

About iskandar vs alexander ............. well I laughed out loud whenever i see any channel in tv showing the comparison. I think some did point out good knock out points. Well as always history is written by different point of view, hence there will many inconsistencies here and there. Just to point out some of my opinion about our history book :
1) Omission of major events :
WWII is the biggest event ever known but only explain in brief
Why ? Cos we are the losers or conquered by the "bad guy" thats like worse than the worst. Thats why the french talk more about napoleon than de gaulle.

2) Inconsistency of facts
If i did remember correctly, the mongols are always excluded from the history, like appear here and there (always elusive)
Why ? Cos they destroy islam civilization. (hulagu, tamerlane)

I can go whole day talking about it but why bore. But I do like some islamic civ especially about saladin. Accepted by friends and rivals alike. But why such a less exposure ? Cos the ultimate prize is jerusalem and currently is under israel. If its not......well you can see the whole history book just touch about crusades (jihad).

And melaka compared to china thing....... I think even a 3 year old can tell you.
