Last year, Lithuania’s President Dalia Grybauskaite openly disagreed with the U.S. on a new reduction plan for the Eastern European missile defence system, planned by the Bush administration, and in perhaps the most shocking move, snubbed U.S. President Barack Obama at a dinner in Prague, even though nearly every other Eastern European president attended.

Since becoming Lithuania's president in 2009, she has wasted no time defining her leadership. "Yes, you have to be a strict and loud partner if you want to be heard in the conversation," Grybauskaite, 55, told The Associated Press in an interview this week.

After the Obama administration, along with Russia, unfurled a strategic missile reduction plan — dubbed New Start — Grybauskaite was the only ally who criticized it, claiming the plan harmed Lithuanian security.

"Lithuania is not used to a straightforward, terse, forceful way of making statements. I admit using this style in pushing NATO defence plans for the Baltic states," she said.

U.S. cables released by WikiLeaks earlier this year show NATO privately decided in January 2010 to expand a NATO defence plan for Poland to cover members Estonia, Latvia and Lithuania.

"I am afraid that if I had chosen a different tone, Lithuania and its neighbours would be still waiting another six years for these," she said to the Associated Press, giving herself credit for USA’s and NAYO’s new strategy as revealed by WikiLeaks.

It remains to see how her latest claims of successful ‘forceful statements’ will be received and viewed by the White House, but the U.S. – Lithuanian relationship has hardly been strengthened by her comments.
