Why they needed a large network of support:
[1] Faked papers
[2] Money to live
[3] Money for flight training

The situation is much different yes, but is the enemy? Japan at that time basically had a cult of Emperor worship, they were as warlike and homicidal as any county in the world then or now. I suggest you read ‘the rape of Nanking’. What is Japan like now?
Is it going to be difficult to find Bin Laden? Yes. It will not however be difficult to find the countries that support him, with his support removed he will be ineffective.
