This trick has been played many times by numerous countries throughout history.

... Some caution must be given concerning Bob Chapman. He is bold and intrepid, but half of his shocking calls have been nothing more than hot wind that passed to the desert hills. For three years, he has been warning of bank shutdowns and bank holidays. The Jackass has expected them eventually, but Chapman gave at least three such wrong calls. He has been alarmist at times, but his calls are surely contingency plans in the shadowy conference rooms where the elite meet and the security agencies map out logistics. At times Chapman seems to lack some comprehension of practical implications. But he does have some deep sources. The best approach for this information is to plan on it in the future, but that door might not open for some time. The timetable will be dictated by events, which are unquestionably turning more toward chaos and disorder.
