Such an approach is not unhelpful in pre-trial shenanigans, where it is one party dealing with another party. Pre-trial litigation is often deal-making by another name. But when a dispute gets to court (and most Trump-related litigation does not get to a courtroom) then such bilateral game-playing becomes far less important. A third party - the judge (and sometimes jury) takes power. Trump’s blustering and bargaining is not well suited for this. Bullying will now not be enough.
