Describing "Islamic extremist terrorism" as the enemy of the US, former New York Mayor Rudy Giuliani has appealed Americans to vote for Republican presidential candidate Donald Trump to commit themselves to "unconditional victory" against the menace.
"In the last seven months, there have been five major Islamic extremist terrorists attacks on us and our allies. We must not be afraid to define our enemy. It is Islamic extremist terrorism," Giuliani said in his address to Republican National Convention here.
"I did not say all of Islam. I said Islamic extremist terrorism. Failing to identify them properly maligns decent Muslims around the world. It also sets up a fear of being politically incorrect that can have serious consequences. And it has. This is why our enemies see us as weak and vulnerable," he said.
"Donald Trump has said the first step in defeating our enemies is to identify them properly and see the connections between them. To defeat Islamic extremist terrorism we must put them on defence. If they are at war against us, which they have declared, we must commit ourselves to unconditional victory against them, the former New York Mayor said.
"This includes undoing one of the worst deals America ever made, Obama's Nuclear Agreement with Iran that will eventually let them become a nuclear power and put billions of dollars back into a country that the world's biggest state sponsor of terrorism," he alleged.
"Donald Trump will make sure that any agreement with Iran meets the original goals of the UN and our allies: a non-nuclear Iran. Donald Trump is a leader. He will reassert America's position as the nation with the best values to lead the world," he said asking people to overwhelmingly support Trump in the November elections.
Giuliani said Democratic presidential candidate Hillary Clinton, is not good for the country.
"You know Donald Trump will secure our borders. His opponent has had her chance to do this and failed. Hillary Clinton is for open borders. She is in favour of taking in Syrian refugees even though the Islamic state has told us they are going to put their operatives in these groups so they can carry out terrorist acts against us and our allies," he said.
"We can't afford to repeat the mistakes of the past. Hillary CIinton's experience is the basis for her campaign. Well, Hillary Clinton's experience is exactly the reason she should not be our president. There is no more time for us left to revive our great country. No more time to repeat our mistakes of the past," he said.
"Washington needs a complete turnaround and Donald Trump is the agent of change and he will be the leader of the change we need," Giuliani said.
Alabama Senator Jeff Sessions said Trump is the leader that will bring change.
"He has the strength, courage, and will to get it done. He is attracting more and more Independents and Democrats to our movement," he said.
Lieutenant General (retired) Michael Flynn said that because of Obama's ill-advised actions, the world has lost faith in American leadership and the threats are mounting.
"Radical Islam metastasising throughout the world. What keeps me up at night is the sobering realisation that evil exists. The radicalisation of Islam and its barbaric cause that uses modernity to influence potentially millions around the world to join their cause should keep us all upat night," he said.
"We must take seriously the possibility that these enemies have weapons of mass destruction and intend to use them. We must understand and define our enemies if we intend to defeat them," he added.
"America and Americans deserve no less! Because Obama chose to conceal the actions of terrorists like Osama bin Laden and groups like ISIS, and the role of Iran in the rise of radical Islam, Americansare at a loss to fully understand the enormous threat they pose againstus," he said.
Pat Smith, whose son Sean was one of four brave Americans killed during the 2012 terrorist attack at Benghazi, held radical Islam responsible for it.
"And, when it comes to the threat posed by radical Islamic terrorism, he will not hesitate to kill the terrorists who threaten American lives. He will make America stronger, not weaker. This entire campaign comes down toa single question," Smith said.
