We've screwed up Haiti so bad that it appears we can't invade directly.
Instead the U.S. is going to underwrite the next foreign occupation of Haiti.

The U.S. and Kenya signed a defense agreement Monday that will see the East African nation get resources and support for security deployments as it is poised to lead a multi-national peacekeeping mission to Haiti to combat gang violence.

Haiti's acting President has been asking for international intervention for months.
Haiti is indeed falling apart, but just focusing on the gang violence is a mistake for a couple reasons. The big reason is that President Henry is one of those behind the violence.

because the gangsterisation of the country is linked to the PetroCaribe scandal (the embezzlement of $2 billion in aid from Venezuela by multiple Haitian governments that led to political unrest in 2018). That is when the team of Jovenel Moïse (the president assassinated in July 2021), instead of mobilising the state’s institutions and justice to go after those who stole the funds, started arming gangs and going after residents of low-income neighbourhoods to stop them from protesting. So, if a force arrives without a political agreement that fosters governance and a state of rights, it will be to protect the status quo, to protect the interests of those who gangsterised the country, and the population will continue being a victim.
...
because the government controls the gangs and since they perceive the force as a support to the team in power, they will ask gangs to let the population circulate. But it won’t be a long-term help.

Once the electoral process starts, those gangs will be very active and control it. They will be the ones choosing the president, the senators, congressmen, judges, and mayors. They will win the elections, even though casting your ballot is supposed to be a democratic exercise that allows people to choose freely. I don’t see a force and the current government organising elections without having chaos afterwards.

Haitian-American leaders are calling on Biden to end his support for the Henry government.

“Any military intervention supporting Haiti’s corrupt, repressive, unelected regime will likely exacerbate its current political crisis to a catastrophic one,” they wrote.
“It will further entrench the regime, deepening Haiti’s political crisis while generating significant civilian casualties and migration pressure.”

However, the Biden Administration is unlikely to change anything. Even while the Biden Admin is telling Americans it's too dangerous to travel there, it is increasing deportations to Haiti.
Another reason not to support this is because Henry became president of Haiti by assassinating the last corrupt president, in a very Game of Thrones sort of way.

The failed raid is just one example of Haitian investigators being thwarted in their attempts to investigate the assassination of the president.

Multiple law enforcement sources have told CNN one man lies at the center of much of that obstruction: Ariel Henry. We are not identifying them for security reasons.

Those sources say they have laid out a series of questionable actions that, they say, detail the Prime Minister’s alleged involvement in the assassination: both in plotting Moïse’s death and in helping orchestrate the subsequent cover-up. And, when two of the top judicial authorities sought potential charges against him, they were fired.
“Ariel (Henry) is connected and friends with the mastermind of the assassination. They planned it with him. Ariel is a prime suspect of Jovenel Moïse’s assassination, and he knows it,” Orélien said in the recording, obtained exclusively by CNN.
