Turmoil in Poland.

On the morning of 10 April a Polish plane carrying the Polish President and a high ranking team of politicians and military men, due to land in Smolensk, crashed killing all those on board. The event marks the end of an estrangement between Poland and Russia which can be traced to the outbreak of the Second World War. It also might become the beginning of what most hope will be a period of constructive co-existence which will be marked by realpolitik rather than nationalist posturing.
