It is a hard truth to accept. The world we live in can change without warning, as recently seen in Syria, Libya, Egypt, Ukraine and many other countries. Including terrorist incidents, active conflicts over the last year have affected 54 of our 196 countries worldwide. This is more than 1/4th of the world.
We all wish such situations will never affect us however, if it did, the ability to pack your bags and move your family immediately to safety without any delay is priceless. Furthermore, the ability to leave and continue life in an economically sound country with top educational institutions and endless work and lifestyle opportunities would be a miracle. This is all possible when you have citizenship rights in multiple countries.
