The Swedish government allowed bad people inside of Sweden - one of them murdered Ebba Åkerlund and others in Stockholm in 2017.

If the Swedish government allows US military forces inside of Sweden, it is very likely that US military forces will murder Swedes.

Further, US military forces inside of Sweden will treat Sweden like a toxic landfill and poison the Swedish environment and Swedish people - the same way the US military poisons Americans and others that live near US military bases.

Overseas bases can indeed reassure allies, but in some cases, this strategy may work too well and risks making allies complacent in their own defense postures, content to free-ride off the United States’ largesse with little incentive to spend more on their own capabilities.

A U.S. military presence can stoke resentment among local populations and their leaders, alienating the allies that bases were intended to reassure. Labor violations, criminal conduct by U.S. soldiers, and violations of sovereignty that occur at or near U.S. military bases can jeopardize delicate diplomatic relationships and fuel anti-U.S. movements among locals.

Osama bin Laden famously cited the presence of U.S. troops on foreign soil as one motivation for the 9/11 attacks. In November 2002, he wrote, “Your forces occupy our countries; you spread your military bases throughout them.”

Members of the 24th Infantry were guilty of the racially-motivated murder of 15 white Houstonians, seven of whom were civilians. The US troops were not trying to quell a race riot; they were the race riot.

Sergeant Henry led over 100 armed soldiers toward downtown Houston by way of Brunner Avenue and San Felipe Street and into the Fourth Ward. In their two-hour march on the city, the Blacks killed fifteen Whites, including four policemen, and seriously wounded twelve others, one of whom, a policeman, subsequently died. Four Black soldiers also died. Two were accidentally shot by their own men, one in camp and the other on San Felipe Street.

Austin congratulated the Afghan military for having “retaken and reestablished security in key areas, such as Kunduz.” He did not mention that the battle for Kunduz involved a U.S. aircraft attacking a hospital and killing 42 civilians — doctors, nurses, patients. It was the kind of civilian slaughter that typified U.S. military operations. Austin and an entire generation of generals did their best to avoid mentioning these inconvenient details, denying them unless they were confronted with irrefutable evidence, and then doing little in the aftermath to prevent these atrocities from reoccurring.
