US officials privately brief British Prime Minister David Cameron. In his first visit to Washington, DC, as prime minister, Cameron is briefed by General James Cartwright, vice-chairman of the Joint Chiefs of Staff. According to a later account by the Guardian, Cartwright tells Cameron that the ISI, Pakistani’s intelligence agency, is at least tolerating terrorism, and may be promoting it. The Guardian will add that Cameron “was not just told in Washington that organizations like Lashkar-e-Toiba were able to launch attacks on India and Britain from Pakistan. Cameron was also warned that Pakistan was providing a haven for al-Qaeda leaders, possibly including Osama bin Laden.” [Guardian, 5/2/2011] Exactly one week after this briefing, Cameron will publicly accuse Pakistan of supporting and exporting terrorism (see July 28, 2010). This briefing takes place the same month US intelligence makes a key intelligence breakthrough that soon leads to bin Laden’s hideout in Abbottabad, Pakistan (see July 2010 and May 2, 2011).
