Given the inherent chicanery, deceit and deviousness of intent involved in Whataboutery, it is the favoured means of those who seek to hide their own misdoings and lack of credible answers. Authoritarian leaders who typically slam all forms of opposition voices and democratic concerns, are naturally drawn towards Whataboutery than essentially democratic, open and honest political leaders. In modern democracies the wave of uber-nationalistic fervour has ensured that democracies are now led by the likes of nationalistic leaders like Shinzo Abe, Boris Johnson, Recep Erdogan, Scott Morison, Benjamin Netanyahu etc.
