United States President Donald Trump has sparked mixed reactions after he ordered the US Navy to shoot down and destroy any and all Iranian gunboats should they harass the US ships.

Through his Wednesday afternoon tweet, Trump said Iranian gunboats shall not be spared if they cross ways with the Americans.

"I have instructed the United States Navy to shoot down and destroy any and all Iranian gunboats if they harass our ships at sea," he tweeted.

His tweet has sparked mixed reactions from the Americans, with some urging him to focus on COVID-19 pandemic instead of picking wars with Iran.

Others are siding with Trump on what they are saying to be 'clearing the mess' the former President Barack Obama left behind.

Here are some reactions taken from Twitter.

Nick Jack Pappas said: "We have enough to worry about at home without Trump's inept leadership provoking a war, too."

Andy Ostroy said: "You're nothing but a miserable, angry, ignorant, unqualified, incompetent, insecure, self-loathing, irresponsible, reckless, dangerous SOCIOPATH..Such a big tough guy on Twitter. Too bad when it was YOUR turn to suit up like a REAL MAN and defend America you hid behind your rich daddy like a draft-dodging COWARD

Heshmat Alavi said: "The mullahs' regime ruling #Iran harasses UN Navy ships for propaganda purposes. Thank you, President Trump, for reminding this regime that the Obama years are gone. And BTW, this regime does not represent the Iranian people.

DeAnna Lorraine said: "Thank you for keeping us safe against bad actors. This is all Obama's fault. He's the one who emboldened them by sending pallets of cash in the dead of night.
