While there is some dispute as to the matter of influence, Popper had a long-standing and close friendship with economist Friedrich Hayek, who was also brought to the London School of Economics from Vienna. Each found support and similarities in the other's work, citing each other often, though not without qualification. In a letter to Hayek in 1944, Popper stated, "I think I have learnt more from you than from any other living thinker, except perhaps Alfred Tarski." Popper dedicated his Conjectures and Refutations to Hayek. For his part, Hayek dedicated a collection of papers, Studies in Philosophy, Politics, and Economics, to Popper, and in 1982 said, "...ever since his Logik der Forschung first came out in 1934, I have been a complete adherent to his general theory of methodology."

On 27 June, the ICC issued arrest warrants for Gaddafi, his son Saif al-Islam, and his brother-in-law Abdullah Senussi, head of state security, for charges concerning crimes against humanity. Libyan officials rejected the ICC, claiming that it had "no legitimacy whatsoever" and highlighting that "all of its activities are directed at African leaders". That month, Amnesty International published their findings, in which they asserted that many of the accusations of mass human rights abuses made against Gaddafist forces lacked credible evidence, and were instead fabrications of the rebel forces which had been readily adopted by the western media. Amnesty International did however still accuse Gaddafi forces of numerous war crimes. On 15 July 2011, at a meeting in Istanbul, over 30 governments recognised the NTC as the legitimate government of Libya. Gaddafi responded to the announcement with a speech on Libyan national television, in which he called on supporters to "Trample on those recognitions, trample on them under your feet ... They are worthless".
Who is Gaddafi's brother-in-law?
Abdullah Senussi

Kerry said on September 9 in response to a reporter's question about whether Syrian President Bashar al-Assad could avert a military strike: "He could turn over every single bit of his chemical weapons to the international community in the next week. Turn it over, all of it, without delay, and allow a full and total accounting for that. But he isn't about to do it, and it can't be done, obviously." This unscripted remark initiated a process that would lead to Syria agreeing to relinquish and destroy its chemical weapons arsenal, as Russia treated Kerry's statement as a serious proposal. Russian Foreign Minister Sergey Lavrov said Russia would work "immediately" to convince Syria relinquish and destroy its large chemical weapons arsenal. Syria quickly welcomed this proposal and on September 14, the UN formally accepted Syria's application to join the convention banning chemical weapons, and separately, the U.S. and Russia agreed on a plan to eliminate Syria's chemical weapons by the middle of 2014. On September 28, the UN Security Council passed a resolution ordering the destruction of Syria's chemical weapons and condemning the August 21 Ghouta attack.
Which country convinced Syria to actually give up its chemical weapons?
