President Barack Obama has called for the German people, and by extension Europe, to trust that the US is not infringing on their privacy, despite the Snowden leaks.
Obama issued the call for "trust" about the PRISM leaks during a joint press conference with German chancellor Angela Merkel when asked how the leaks have affected the two nations' relationship.
"There's no doubt that the Snowden revelations damaged the impressions of Germans with respect to the US government and our intelligence cooperation," he said.
"What I would ask would be that the German people recognise that the US has always been at the forefront of trying to promote civil liberties, and that we have traditions of due process that we respect.
"And so occasionally I would like the German people to give us the benefit of the doubt, given our history, as opposed to assuming the worst. Assuming that we have been consistently your strong partners and that we share a common set of values."
Obama's plea follows widespread concerns about the National Security Agency's (NSA's) intelligence gathering practices.
The concerns erupted in 2013 when whistleblower Edward Snowden leaked documents to the press proving that the agency siphons vast amounts of web user data from firms including Microsoft, Apple, Yahoo and Facebook.
Reports also broke suggesting that the NSA may have tapped Merkel's phone as part of the surveillance.
The leaks led Deutsche Telekom to consider routing local internet traffic through domestic servers only in a bid to protect customers.
Obama has moved to allay these concerns in several speeches since the leaks, including his 2014 State of the Union address, and has announced plans to re-examine and create new legislation around intelligence agencies' data collection.
Obama cited the promises as proof that the US has done enough to allay European governments' and businesses' fears, but added that further debate about cooperation between the two regions' intelligence agencies is needed.
"We've taken some unprecedented measures, for example, to ensure that our intelligence agencies treat non-US citizens in ways that are consistent with due process and their privacy concerns," he said.
"If we are trying to track a network that is planning to carry out attacks in New York or Berlin or Paris, and they are communicating primarily in cyber space, and we have the capacity to stop an attack like that, it requires us being able to operate within that cyber space."
Merkel said that, while she agrees on a need for cooperation in cyber space, there are still key questions the US must answer about its surveillance operations.
"On the NSA issue I think there are still different assessments on individual issues there, but if we look at the sheer dimension of the terrorist threat we are more than aware of the fact that we need to work together very closely," she said.
"There are other possibilities, through the cyber dialogue for example, to continue to talk about the sort of protection of privacy versus data protection and so on, and security. But combating terrorism was basically in the forefront today."
Merkel's comments follow a wider call for answers regarding the NSA's activities. The Electronic Freedom Foundation called in January for further major legislative change and increased transparency about intelligence agencies' activities.
