At the time of the 9/11 attacks, the US did not have bases in in Afghanistan, Iraq or Libya. Bin Laden was complaining about US presence in Saudi Arabia and Israel. So even with recent withdrawals, the US presence is only back at the level at the tine of the attacks. I don't see how this can in any way be construed as successful?

The purpose of the 9/11 attacks was to get the American public to demand the US withdraws support to Israel and Saudi Arabia. This has clearly failed.
