Lawfare is a relatively new term. In essence, it is the weaponization of bourgeois law, usually by the right wing. Various US supporters of Donald Trump would argue that his prosecutions also fall under this mantle, despite the fact that he has skated out of almost every attempt to prosecute him so far. However, this essay is not about Donald Trump. God knows there are enough of them on that subject.
In Latin America, lawfare has been mostly used to try and eliminate leftist opponents who operate within the confines of bourgeois law.
