"We must make a decision," Yushchenko said at a meeting with Parliamentary Speaker Oleksandr Moroz, Prime Minister Yuriy Yekhanurov, representatives of all parliamentary factions, and leading politicians.
Yushchenko said there were only two ways out of the deadlocked situation, either confrontation or the real unification of the nation.
He added that it was up to politicians to choose the nation's strategy.
Yushchenko is now facing a dilemma between confirming Viktor Yanukovych, his "orange" revolution rival, as prime minister or dissolving parliament - the right he received after the assembly missed a 60-day deadline for forming a new government on Tuesday. He has until August 2 to decide how to respond to Yanukovych's nomination.
