Miami: US Democratic presidential nominee Hillary Clinton said on Tuesday in Tampa that the campaign of her Republican rival, Donald Trump, is "one long insult to all those who have worn the uniform". At a campaign rally at the University of South Florida, Clinton also harshly criticised Trump's recent trip to Mexico, characterising it as an "embarrassing international incident" that ended with a "Twitter war with the President of Mexico", EFE news reported. "He is temperamentally unfit and totally unqualified to be President of the United States," she said. In the final two-month stretch of the presidential campaign, culminating in the November 8 election, Clinton is fighting to garner more voter support in key states such as Florida, a central element in both parties' strategies to win the White House. On Tuesday, the former Secretary of State warned that, in terms of fighting terrorism, Trump is placing the United States in even greater danger than it already is in with a "secret" plan to destroy the Islamic State, saying that the secret is that he doesn't actually have a plan. "He called the military a disaster," Clinton said. "He said, 'I know more about ISIS than the generals do.' His words are an insult to our people in uniform." She then promised to help the military by giving it the proper tools to "dismantle terror networks", saying that "we will do everything it takes to end the Islamic State's reign of terror and bring them to justice". Clinton said that in the wake of the 9/11 terrorist attacks, she -- as a New York senator -- "worked to make our country safer and to rebuild New York and the Pentagon. But I always, always was determined to do anything I could to bring (Al Qaeda leader Osama) Bin Laden to justice". She emphasised her role in helping to kill Bin Laden, noting that she was on hand with President Barack Obama and top intelligence officials on the night a SEAL team tracked down and killed the terrorist chief in Pakistan. Recently, the former Secretary of State has focused on criticising Trump's off-the-cuff and unpredictable foreign policy statements to attempt to show he is unfit to be commander-in-chief, EFE news added. She made an effort in her Tampa remarks to gain the support of so-called "millennials", voters born between 1980 and 2000, promising to fight for an economy that works for all Americans, not just for the ones on top, pushing for renewable and clean energy sources, including solar power, and making young people a part of that process. Clinton also referred to her commitment to fight climate change, global warming and sea level rise, issues, she said, in which Trump does not "believe".
