The problem in the OP could partially be solved by clicking B to change camera view, and +1 for the pause button or if bringing up the main menu could stop the action (at least for casual difficulties).
Yes, I'm aware of tactical view and zooming in, and I'm also aware that's a terrible half-assed solution to a problem that honestly shouldn't even have made it through focused playtesting. It still doesn't actually fix the problem, just makes it LESS LIKELY to occur.
