Following the 2003 invasion of Iraq, American intelligence agencies reported that aides of Saddam Hussein managed to acquire Belarusian passports while in Syria, but that it was unlikely that Belarus would offer a safe haven for Saddam and his two sons. This action, along with arms deals with Iraq and Iran, prompted Western governments to take a tougher stance against Lukashenko. The US was particularly angered by the arms sales, and American political leaders increasingly began to refer to Belarus as "Europe's last dictatorship". The EU was concerned for the security of its gas supplies from Russia, which are piped through Belarus, and took an active interest in Belarusian affairs. With the accession of Poland, Latvia and Lithuania, the EU's border with Belarus has grown to more than 1000 kilometers.
