Obama: From Tbilisi to Tunis, if you have democracy we will be your partner

United States President Barack Obama has promised those willing to do the hard work of building democracy will have the US as a partner to their nation.

Speaking in Warsaw to mark 25 years since the fall of communism in Poland, he condemned Russian aggression in Ukraine.

"We stand together because we know that the spirit of Warsaw and Budapest and Prague and Berlin stretches to wherever the longing for freedom stirs in human hearts, whether in Minsk or Caracas, or Damascus or Pyongyang,” Obama said.

"Wherever people are willing to do the hard work of building democracy – from Tbilisi to Tunis, from Rangoon to Freetown – they will have a partner in our nations.”

In Warsaw speech Obama reiterated his new initiative to bolster the security of NATO allies and increase America’s military presence in Europe, including supporting Ukraine, Moldova and Georgia.

He spoke about his plan today and said creating a $1 billion fund would allow more US military and equipment to be introduced throughout Europe.

"And it will mean increased support to help friends like Ukraine, and Moldova and Georgia provide for their own defense,” he said.

He believed this would mean countries could respond quicker to a crisis. The money would also go towards setting up "additional exercises and trainings to keep our forces ready … in the air, and sea, and on land.”

Obama condemned Russian aggression in Ukraine and asked: "How can we allow the dark tactics of the 20th Century to define the 21st".
