President Barack Obama delivers his final address on the fight against terrorism Tuesday, in a speech aimed at his successor who has not yet publicly outlined his own anti-terror strategy.Speaking from MacDill Air Force Base – the Florida headquarters of the Special Forces Command and CENTCOM, command for the US military in the Middle East – Obama will give a rundown of operations in places like Afghanistan, Iraq and Syria during his two terms in office.Obama will touch upon his failed bid to close the Guantanamo military prison in Cuba and his continued strong opposition to the use of torture – positions greeted with scorn by President-elect Donald Trump during the campaign.Obama, who ordered the successful raid against al Qaeda leader Osama bin Laden in 2011, also intends to underscore the "complexity" of the fight against terror, according to top advisor Ben Rhodes."That's something you can only experience as president," Rhodes said, adding it will be crucial for the future US administration to precisely understand the threat, maintain strong relations with allies and pair military action with clear diplomacy.In particular, Rhodes stressed, it is necessary to keep in mind "who we are as a country".Trump, who has pledged to upend his predecessor's entire agenda including foreign and security policy, takes over in the White House in just over six weeks.On the campaign trail he pledged to restore waterboarding – a form of simulated drowning widely regarded as torture – and permit "far, far worse".Obama, in contrast, banned extreme CIA interrogation techniques used on terror detainees as soon as he took office.He has long argued that such practices are ineffective, violate American values and hand militants a potent recruiting tool for groups like the Islamic State (IS).The US president also plans to defend his warfare tactics against IS militants in Iraq and Syria: no ground troops but military support for local security forces, and an intense air campaign with support from an international coalition.Since his election, Trump seems to be to modifying his views on waterboarding – a change that may reflect the influence of his nominee to head the Pentagon, retired marine general James Mattis.Mattis appears to have convinced Trump to rethink his stance on torture, after reportedly telling the real estate mogul that he is unconvinced about its effectiveness during interrogations."He said, 'I've never found it to be useful'," Trump told the New York Times in a wide-ranging interview with reporters and senior editors last month.Mattis told Trump that winning a prisoner's trust is a far more effective way of prying information from him.'"Give me a pack of cigarettes and a couple of beers and I'll do better,"' Trump told staff members at The Times, recounting what the general had told him."I was very impressed by that answer," he said.As the handover nears, and Trump and his top advisors prepare to roll back Obama's policies, the White House seems intent on highlighting the progress made of security issues under the outgoing president's leadership.Administration officials point to the recovery of almost half of the territories controlled by IS in 2014, the ongoing offensive in Iraq, and a slowing of foreign fighters joining the ranks of the extremists.Trump has not yet announced a nominee to head the State Department and has been vague at best about how he plans to defeat IS, but during months on the campaign trail he emphasized that in order to win, it was essential that America be "unpredictable".And he has ridiculed Obama for refusing to brand IS an “Islamist” threat – a term that the Democratic president has avoided, for fear of offending Muslims around the world.Trump also boasted late last year that on the subject of IS, he knows "more than the generals".In the waning days of his presidential campaign, Trump said he would get a detailed plan from his military brain trust on beating IS once and for all."They'll have 30 days to submit to the Oval Office a plan for soundly and quickly defeating ISIS," Trump said in a campaign speech in September.
