If you say history repeats itself, when was  Trump last assassinated? I really do not understand this. 

I guess our different views on the world are incompatible. I would prefer to have forecast model which could be proven/disproven with a statistically significant number of tests/historically events. It should also be firmly based on physical reality. For instance if you drop an object it will fall to the ground. 

Truth is that reality is a caotic place where all sort f things happens all the time. You will always be able to retrofit a cyclic model to the historical events. If the events does not fit your model, you can always correct the cycle or add rules that evey third or fourth cycle should be skipped. How do you know you wont have to add a new rule next time, or perhaps something happens in between the cycles?

Examples of what I mean fits a cyclic model; the seasons ,winter, spring, summer and autoumn; the moons way around the earth; elections in democratic contries.

Events in the world are simply to caotic to be predicted in a simple cyclic model. It is probably impossible to make a forecast model which could predict historical events, but that is my view.

I have heard people foreseing the killing of Trump since day one. None have been right so far. Regarding the impeachment I feel that the last events today indeed prove that Trump is loosing it. It seems there is no plan behind the killing of the Iranian general. Suddenly John Bolton wish to speak to the senate, the US firstly says they will withdraw all trops from iraq, and only one hour after they will not. Its truly become a mess!!! The really sad thing is that its a big gamble with the lifes of  both US soldiers and lifes all over the middle east. Nancy Pelosy is correct that impeaching the president is a tragedy! This goes both for the world, but foremost for the USA.
