The only political ism surviving in full strength from the past is nationalism. This was partly to be expected from the liberation of so many colonies simultaneously, beginning in the 1920s. But this nationalism differs from the old in two remarkable ways: it is not patriotic and it does not want to absorb and assimilate. On the contrary, it wants to shrink and secede, to limit its control to its one small group of like-minded-we-ourselves-alone. It is in that sense racist, particularist, sectarian, minority-inspired.
