Removing term limits would mean repealing the 22nd amendment, which Trump won't successfully be able to do given the numbers required to do so.
The Supreme Court also isn't going to "interpret it differently" as the amendment is also incredibly cut and dry in its description, because it was written in the 1950s to be very cut and dry.
But let's say somehow Trump manages to find a way to get enough people to vote and repeal it - that would then open up the floodgates for previous democratic presidents like Obama to run ahain against Trump. It would also open the risk to the Republicans wherein if a Democratic president gets elected and is so overwhelmingly popular, they could also run indefinitely.
This would also prevent certain other republican hopefuls, like DeSantis, from being able to run for President if an incumbent Republican president remains too popular to be voted down.
The only way for the repealing of the 22nd amendment to work in Trump's favor would be to create a new amendment that only allows Republicans, or Trump, to run for more terms, which would be even more impossible to ratify.
Trump has proven time and time again he has no idea how the constitution or amendment process works. This is him, once again, flapping his mouth without any understanding of how the process works, and probably believes if he stomps his feet hard enough, he'll get his way, like he did when he threw his temper tantrum back when he lost in 2020.
Stop dooming - Trump isn't going to find a way to repeal the 22nd amendment, and unlike the 2nd amendment, there's not much open for interpretation for the 22nd.
