The remarks came shortly after Maduro forcefully warned the USA president that Venezuela "will never give in".
"Venezuela is not very far away and the people are suffering".
Trump said on Friday he would not rule out a "military option" in Venezuela, a claim seemingly contradictory to the view of his top national security adviser Michael Flynn.
"We are all over the world and we have troops all over the world in places that are very, very far away", Trump said. "I am sure that we will all be on the front lines of defending the interests and sovereignty of this beloved Venezuela", he added.
Venezuela's defence minister Vladimir Padrino said Mr Trump's comments were "an act of craziness".

Argentinean worldwide law expert Paola de Simons told Xinhua that Trump was sending out "a warning, (as a) foreign threat, which belongs to what were decades ago".
The president's comments will also complicate the calculus of Latin American leaders, many of whom had been speaking out against Maduro's actions. Trump has shut the door on the idea until Maduro returns some sanity to his quickly deteriorating nation.
The White House said late Friday that Maduro requested a phone call with Trump.

Will Tottenham start slowly again? So why aren't players arriving? Arsenal faced similar issues from the mid- to late-noughties. This will be a repeat of Newcastle's last Premier League game in May 2016 - when they thrashed Spurs 5-1 at St James' Park.
Meanwhile, Venezuela is also being pressurised by Peru, who has criticised its new constituent assembly. Peruvian President Pedro Pablo Kuczynski, who has led Latin America in taking on Maduro, recalled the country's ambassador to Caracas after the government-packed supreme court took steps to shut down congress, which is controlled by Venezuela's opposition.
