美国总统川普星期三将启程前往波兰。川普在华沙会见东欧领导人后，将发表上任后在欧洲的首次重要公开讲话。

白宫说，川普将重申对北约共同防御原则的承诺，但同时也会再次提出，其它成员国要更多地分担北约的财政负担。

目前，波兰驻扎了三千多美军，作为北约部署的一部分，对抗俄罗斯对乌克兰的进犯。

华沙大学教授，政治分析家卢维基说，“我想，大多数波兰人想听的是，美国会继续在波兰驻军，会遵守北大西洋公约的第五条款，在需要的时候帮助我们。”

川普总统将在华沙的克拉辛斯基广场发表讲话。对很多波兰人来说，克拉辛斯基广场具有重要的象征意义，是他们抵抗集权统治的标志。川普的讲台就设在纪念1944年华沙起义的铜质纪念碑下。这座纪念碑是为了纪念几十万反抗纳粹占领军的波兰士兵和平民。波兰起义历时两个月，最后以失败告终。

支持者说，川普在气候变化和移民等很多国际问题上的看法都与波兰现任政府很多重要人物相同。但也有人担心，川普的来访会加剧东西欧之间的裂隙。

反对者计划举行反川普抗议活动，但抗议活动估计会被限制在离克拉辛斯基广场较远的地方。

U.S. President Donald Trump, who departs for Poland Wednesday, is due to meet Eastern European leaders in Warsaw before speaking in the center of the Polish capital, in what will be his first major public address in Europe.

The White House says the president will reiterate his commitment to NATO’s principle of common defense, but also restate his demand that other members contribute more to the alliance's financial burden.

Over 3,000 U.S. troops are stationed in Poland as part of a NATO deployment aimed at countering Russian aggression in Ukraine.

The University of Warsaw's Professor Zbigniew Lewicki, a political analyst, said: “I think most people want to hear that the United States would keep its military presence in Poland, would observe Article 5 of the (NATO) Washington Treaty - meaning coming to our assistance if need be.”

Trump will deliver his speech in the capital’s Krasinski Square, which has deep symbolism for many Poles, commemorating their resistance to totalitarian rule. His podium will stand beneath an imposing bronze monument to the 1944 Warsaw Uprising, honoring hundreds of thousands of Polish soldiers and civilians who died during an ultimately unsuccessful two-month insurgency against the city’s Nazi occupiers.

Supporters say Trump's views on many global issues, such as climate change and migration, are shared with many leading figures in Poland's current government. However, some fear the U.S. president's visit could deepen the growing rift between Eastern and Western Europe.

Opposition groups are set to demonstrate their opposition to Trump. Any demonstrators are likely to be kept far away from Krasinski Square.
