It soon became apparent, however, that political will in Ukraine wasn't quite so black and white. The new president was no rose revolutionary or staunch reformist, and he wasn't elected with 96 percent of the vote as Saakashvili had been in 2004. Poroshenko was a politician and businessman, a classic product of Ukraine's oligarchic system, in which every major business leader is also involved in politics. [...]
Saakashvili built a new, transparent customs terminal (which never went into operation), established a citizens' office (which had to close again temporarily) and tore down fences that had been illegally set up on beaches (they were put up again). He reduced the size of the civil service and sent armed investigators to the state-owned chemical plant OPZ. [...]
The real reason for the rift remains unclear. Saakashvili says that he had a long argument with Poroshenko during a March meeting in Malta. According to Saakashvili, Poroshenko demanded that he behave himself and stick to the rules, insisting that he criticize others and not just Poroshenko himself - and that if he did so, he could continue his career in Ukrainian politics and would get a seat in parliament. If he did not, though, according to Saakashvili's account, Poroshenko said "individual measures" would be taken, though he failed to elaborate.
