Donald Trump on France attack: This is war. When will we learn? It is only getting worse

Donald Trump said if elected president, he would declare war on the Islamic State - hours after quickly seizing on horrific reports of another deadly attack in France to ask his Twitter followers: 'When will we learn?' Trump was responding to reports that 80 people had been
killed and more than 100 injured when a truck carrying weapons and hand grenades plowed into people celebrating Bastille Day in Nice on Thursday evening.

Although it was not immediately clear who was behind the attack, Trump said in an interview with Fox News Channel's The O'Reilly Factor, Trump said: 'This is war.'

He said if he's elected president, he would ask Congress for a declaration of war on ISIS – as unconfirmed reports claimed the terror group had claimed responsibility for the attack.

The 70-year-old said that to fight the terror group, which he called a 'cancer,' NATO should be used 'for a purpose.'

In another interview, Trump called for President Obama to acknowledge the problem was 'radical Islam.'

He also reiterated his call for the United States to tighten its borders and brought up his proposal to ban Muslims from entering the country as a solution.

As news broke of the attack, the billionaire real estate mogul tweeted: 'Another horrific attack, this time in Nice, France. Many dead and injured. When will we learn? It is only getting worse'.

In an interview with Fox News' Great van Susteren later on Thursday night, Trump said 'it's about time' Obama used the term 'radical Islam.'

Although not much is known yet about the attacks in Nice, Tump said: 'Generally speaking, I don't think the people come out of Sweden, OK?

'It's probably, possibly, but if it is indeed radical Islamic terrorism, it's about time that [Obama] would say so, OK?

'It's about time, because you're never gonna solve this problem unless you're gonna define it. People would sigh with relief. If it's radical Islamic terrorism, he oughta say it.'- Daily Mail
