The British forces had a very poor commander (Weasel's right about how pathetic Percival was), & the misfortune to be facing a very able Japanese general.

Weasel's original post in question implied that SG formulated our current "Forward Defence" doctrine out of the Brit's failure to stop the Japs in Malaya.
My contention is that the Brits' defence in WW2 was essentially "Forward Defence" doctrine in action. Brilliant as we may think ourselves to be, we didn't invent this doctrine.

Agreed...There is no doubt Percival was a poor commander compared to Yamashita - one of Japan's ablest.
However, a more recent book like "Singapore Burning" by Colin Smith begins to take a more broad-view of Percival failure. He stops short of exonerating him - that Percival is a weak commander, indecisive, etc is beyond a shadow of a doubt.
But the book examines some of the problems facing him that Yamashita was (unfortunately) free of.
Not my own views, but that of the author:
• Being the attacker, Yamashita held the initiative and never lost it. He decided every move and the Brits had to react accordingly.
• No fault of Percival, Allied forces were not as well-equipped as the Japs. In fact, Percival had long before asked for planes and other assets that he never received.
• Again not his fault, many Allied units were green whereas the Japs were seasoned troops from China.
Furthermore...
• The Japs were a determined homogenous force, the Allies were an uneven patchwork of Brit, Aussies, Indians and local troops all of varying quality. Some Brit, Indian, Aussie units were excellent including a Malay platoon under Adnan. But some others broke and ran sometimes before a shot is fired. An airbase was abandoned even before the enemy approached.
• Some commanders disobeyed Percival and acted on their own initiative. A Royal Navy commander while persuing Jap navy decided not to inform SG HQ command his flotilla was in serious trouble, One Aussie commander shifted his forces during the defence of Singapore opening a gap.
...
The Allies were bad, but they were not hopelessly so. There were excellent troops who gave a very good account of themselves despite the odds. And many heroic sacrifices.
Cowardice and insurbodination by certain units or individuals cannot be blamed on Percival.
Brit intel was mostly good. They knew Jap will land in Thailand. Brit recce planes spotted the Jap armada etc etc. But the follow-up action wasn't so hot.
Against a lesser enemy, these mistakes may not have guaranteed defeat.
But they were fighting against some of the best and most seasoned troops in WW2 under one of the best field commander.
