United Kingdom

Nobody forced her to insist that "ending freedom of movement" was front and centre of her strategy.

Nobody forced her to interpret "leaving the European Union" as meaning the hardest of hard Brexits.

Nobody forced her to install totally incompetent slugs as key players in her cabinet and hang onto them until they hit their own endstops.

Nobody forced her to isolate herself and spurn any attempts by other parties and those on the Remain side to seek some sort of acceptable and workable compromise.

Nobody forced her to call a snap election that eroded her already slim majority and contributed to the current deadlock.

She did all that, and the pitfalls that have arisen are a direct result of that, and were totally predictable.

As T_i_B touches on above, the main reason why May is surviving as Tory leader is the same reason she got the post in the first place. No one else really wants to take on the job in the current circumstances, and the alternatives to her are either too wishy-washy and relatively sane for the Tory headbangers or too barking right-wing to attract majority support.
