NATO countries fear a Republican defeat could push President Donald Trump to "dramatically escalate his attacks" on the alliance, Politico reports. European diplomats estimate that if the Democrats gain control of Congress and limit Trump's actions in domestic policy, he will be able to focus on foreign policy. Possible scenarios include the withdrawal of thousands of additional American troops from Europe and a connection between the continued presence of the United States on the continent with the adoption of a peace agreement on Ukraine by the European countries.
