In a keynote speech on November 13 in London, Blair said Iran faced a "clear strategic choice."
"We offer Iran a clear strategic choice: they help the Middle East peace process, not hinder it; they stop supporting terrorism in Lebanon or Iraq; they abide by, not flout, their international obligations," Blair said. "In that case, a new partnership is possible, or, alternatively, they face the consequence of not doing so, isolation."
Blair said the Iraq conflict needed to be seen as part of what he called a "whole Middle East" strategy.
Blair added that the strategy should start with resolving the Israeli-Palestinian conflict.
