Greece has seen better days.

Talks about the country leaving the European Union have resurfaced after the Greek Parliament failed to elect a president, thus averting a much earlier general election. Parliament's failure also led to an 11 percent drop in the country's stocks on Monday.

David Gordon, president of International Capital Strategies, said in an interview with CNBC's "Squawk Box" on Tuesday that it is unlikely Greece will leave the EU. "But it's not impossible," he said. "Greece doesn't want to leave the EU, but it also wants to restructure its public debt."

Gordon added the Greek desire to restructure its debt will not sit well with Germany and other European countries. "Germany has continued to provide bailouts on the assumption that they're going to be repaid," he said. "The politics here are really getting tough."

Gordon said the new year will bring about many challenges to the continent because of three interrelated developments: Greece's current situation, finding financial support for Ukraine "in the context of continued Russian assertiveness," and the dispute over how to best provide quantitative easing.

"All of this is leading to the rise of anti-European parties in mny European countries," Gordon said. "2015 is going to be a tough year for Europe."
