President Trump says Iran's oil infrastructure is on the verge of facing catastrophic failures as the U.S. naval blockade in the Strait of Hormuz prevents the country from exporting its oil. 

Oil production can't be turned off like a switch. So the oil continues to be produced, but it has nowhere to go. That puts serious pressure on the country's infrastructure. 

"When you have, you know, lines of vast amounts of oil pouring through your system, if for any reason that line is closed because you can’t continue to put it into containers or ships, which has happened to them — they have no ships because of the blockade — what happens is that line explodes from within, both mechanically and in the earth," Trump said on Fox News' "The Sunday Briefing" show. 

Trump said that if these severe failures occur, the country will have to rebuild much of the impacted infrastructure, and there would be lingering problems. 

“In other words, it will always be, if you rebuild it, it's hard to rebuild it all, but it would only be about 50% of what it is right now," Trump said, adding that he thinks Iran is "under pressure" because of the situation.
