The United States of America marked its 250th Independence Day anniversary on Saturday amid nationwide celebrations, political tensions and growing concerns over deep national divisions.

Speaking during Independence Day events at Mount Rushmore National Memorial, Donald Trump warned that American identity is facing a renewed threat, declaring that the country is under attack from domestic radicals and extremists.

According to Channels Television, citing AFP, Trump said there had been attempts in recent years to weaken American values and disconnect citizens from the nation’s history.

The US president accused political opponents on the far-left of posing a threat to the country ahead of November’s midterm elections, describing a resurgence of what he called a “communist menace” in America.

“You do not have to be born here, but you do have to love what we have built,” Trump said during his address.

The Independence Day celebrations come at a difficult moment for the country, with millions of Americans facing extreme heat conditions. Reports indicate that nearly 160 million people are under severe heat warnings, disrupting parades and public gatherings across several cities.

Despite the extreme weather, Trump is expected to headline a major rally on the National Mall in Washington, featuring military flyovers and large-scale fireworks.

The milestone anniversary has also sparked reflection among many Americans on the state of the nation after 250 years of history shaped by progress, conflict, civil rights struggles and global influence.

A recent poll by Quinnipiac University found that 61 percent of Americans believe the country is not fully living up to the ideals outlined in the Declaration of Independence, highlighting the sharp political divide between Republicans and Democrats.

While some citizens expressed frustration over social and political divisions, others remained optimistic about the American dream and the freedoms the country offers.

The 250th anniversary celebrations therefore serve as both a historic milestone and a moment of national reflection as the United States navigates an increasingly polarised political landscape.
