Did tony Blair start the war in Afghan?

Tony Blair, as the Prime Minister of the United Kingdom, played a significant role in the decision to join the U.S.-led invasion of Afghanistan in 2001 following the September 11 attacks. The primary objective was to dismantle al-Qaeda and remove the Taliban from power, as they were harboring terrorists. While he supported the war, it was initiated by the United States, with Blair’s government being a key ally in the coalition. Therefore, he did not start the war, but he was instrumental in the UK's participation.
