The press is making a similar mistake with this deal as it did when Obama handed back $150 billion of Iran's money to Iran. This is not our money that Trump's handing (Obama handed) over. The $20 billion is a swap line which may or may not be drawn on by Argentina. Assuming it's utilized, the USA will buy pesos for dollars. And at some point in the future the USA will exchange those pesos back for dollars at a pre-arranged rate, and probably receive compensation for providing the facility. Unless the deal blows up, the Treasury makes money.
In a separate unrelated deal, the USA bought Argentine pesos on the open market, ostensibly to keep the peso stable. It's now either sitting on a small profit from those transactions, or it's already realized a large profit when the peso rapidly appreciated after election results were announced. Please note that the U.S.'s support for Milei, including the swap line that would presumably be withdrawn if his party lost control, swayed the election. That in turn boosted the value of the peso. And now the USA is sitting on a realized or unrealized profit. Bessent's running the Treasury Department like a hedge fund! Which makes sense, considering he was a hedge fund manager. He was instrumental in George Soros' legendary bet against the pound. Speculating on the value of the Argentine peso when you're Treasury Secretary is probably a better bet than even that.
The Trump administration raised the quota on imported Argentine beef to 80,000 metric tons. Annual consumption of beef in the USA is about 12 million tons per annum, so that's 0.7% of annual consumption. It should remove the quota entirely. The price of beef has become unaffordable for many Americans:

Please look at the chart. If politicians had a quota on oil imports when the price of gasoline was $5.00 a gallon, we'd all scream bloody murder. For some reason the farmers and ranchers get a pass.
I share your (TechPapi, Precious_b, Mort Watt) concerns about the effect of the trade wars on soybean farmers. And even though I far prefer Milei's economic policies over Lula's, would point out Argentina is being treated far different from Brazil. The USA placed 50% tariffs on Brazilian products, even though it has a large surplus in trade and services with Brazil. And so Brazil retaliated with its own tariffs. How much sense does that make? It's like shooting off your nose to spite your face.
