WARSAW (Reuters) - Polish President Andrzej Duda ratified a defence agreement with the United States on Monday that cements a greater U.S. troop presence in the country and he said Warsaw’s relations with Washington should not be affected by the U.S. election.The deal was agreed between Duda and U.S. President Donald Trump over a year ago and aims to bolster the Western military presence on NATO’s eastern flank in reaction to an increased assertiveness by Russia. Joe Biden’s election as the next U.S. president puts Warsaw in a potentially awkward position after it had set great store in its relationship with Trump while straining links with EU allies over democratic values. During the election campaign, Biden had accused Trump of backing authoritarian leaders around the world, mentioning Poland among others. He is expected to review Trump’s decision to withdraw thousands of troops from Germany, although U.S. officials have insisted the agreement with Poland was separate from that move.
