Washington DC [US], February 28 (ANI): US President Donald Trump on Friday (local time) said he is 'not exactly happy' with Iran's handling of negotiations over its nuclear program, stressing that the country cannot possess nuclear weapons.

Speaking to reporters before a trip to Texas, Trump said, 'We haven't made a final decision (on Iran). We're not exactly happy with the way they're negotiating. They cannot have nuclear weapons. And we're not thrilled with the way they're negotiating. So we'll see how it all works.'

'I am not happy with the fact that they are not willing to give us what we have to have. I'm not thrilled with that. We'll see what happens. We'll have some additional talks today. But, no, I'm not happy with the way they're going.'

The third round of negotiations between Iran and the United States took place in Geneva on Thursday and another round talks will be held today.

The US president emphasised that he prefers not to use military force against Iran, but admitted that there are situations where it might be necessary.

'There's always a risk... It would be wonderful if they negotiate in good faith and conscience. But they are not getting there,' he said.

On the possibility of a regime change in Iran post US military action, he said, 'Nobody knows. There might be, and there might not be. It would be nice if we could do it without, but sometimes you have to do it with. We have the greatest military anywhere in the world. I'd love not to use it.'

Meanwhile, a day earlier, Iran's Foreign Minister Abbas Araghchi said 'good progress' was made after long and intensive talks in the third round of negotiations with the US in Geneva on issues of Tehran's nuclear programme and sanctions relief discussed amid escalating tensions between the two sides.

Further, Trump said the Cuban government is in serious financial trouble and is in discussions with the United States.

'The Cuban government is talking with us. They're in a big deal of trouble. They have no money. They have nothing right now. But they're talking with us... We could very well end up having a friendly takeover of Cuba,' he said. (ANI)
