US President Donald Trump accepted his party's re-nomination on a massive White House South Lawn stage on Thursday night.

As troubles churned outside the gates, Trump painted an optimistic vision of America's future, including an eventual triumph over the coronavirus pandemic that has killed more than 175,000 people, left millions unemployed and rewritten the rules of society. But that brighter horizon can only be secured, Trump asserted, if he defeats Joe Biden, against whom he unleashed blistering attacks meant to erase the Democrat's lead in the polls, reported India Today.

"We have spent the last four years reversing the damage Joe Biden inflicted over the last 47 years," Trump said. "At no time before have voters faced a clearer choice between two parties, two visions, two philosophies or two agendas."

Presenting himself as the last barrier protecting an American way of life under siege from radical forces, Trump declared the Democratic agenda as "the most extreme set of proposals ever put forward by a major party nominee."

As his speech brought the scaled-back Republican National Convention to a close, Trump risked inflaming a divided nation reeling from a series of calamities, including the pandemic, a major hurricane that slammed into the Gulf Coast and nights of racial unrest and violence after Jacob Blake, a Black man, was shot by a white Wisconsin police officer.
