美国副总统万斯20日受访时称，欧洲国家须为乌安全保障承担"最大份额""发挥主导作用"，美国不应在乌安全保障方面承担重任。美国"在弄清楚 需要采取哪些必要措施结束战争前，不会做出任何承诺"。他还表示，目前乌"想要安全保障"，俄"想要一定数量领土"，相关方面"正在努力"，但 尚未敲定俄乌谈判的所有细节。 据塔斯社报道，俄外长拉夫罗夫20日表示，在没有俄方参与的情况下讨论安全保障问题是"空想"，是一条"死胡同"。俄方愿就解决乌克兰问题展 开任何形式谈判，只要谈判是"真诚"的。他称，高层会晤须在所有前期阶段都"经过最谨慎的准备"后才能举行。只有这样，才不会导致局势恶 化，而是能够真正解决问题。俄安全会议副主席梅德韦杰夫20日在社交媒体上称，俄方已明确表示，绝不接受向乌派驻任何以所谓"维和部队"为 名的北约部队，俄不会接受这样的"安全保障"。 近期，普京同泽连斯基的会晤地点等也引发关注。路透社21日称，匈牙利外长西雅尔多表示，匈牙利已准备好成为俄乌和平谈判的举办地，并为 此创造公平安全的适宜条件。同时，瑞士、奥地利、白俄罗斯方面均表示，愿组织两人的会晤。对于会晤地点，泽连斯基表示，应在"中立"的欧 洲国家举行，并排除了 ...

时隔半年，上次"白宫之辱"留下的心理阴影还没消失，特朗普再次邀请泽连斯基去白宫会晤。 "可怕"的是，这次的背景与上次如出一辙： 上次特朗普在会见泽连斯基之前，和普京有过一次长时间且富有成效的对话，大大拉近了俩人的关系。 这次，特朗普和普京在阿拉斯加峰会上又一次拉近了彼此的距离，亲密关系溢于言表。唯一的区别是， 上次俩人在电话里的勾兑外人无从知晓，而这次全世界却都见证了俩人的"兄弟情"。 不知是特朗普自己动了恻隐之心，还是团队提醒他体谅小泽的心有余悸，总之，他这次在邀请乌克兰总 统再次来访的同时还特意叮嘱了一句：你若愿意，也可以带上欧洲其他国家的领导人一起来…… 就这样，硬着头皮"再入虎穴"的泽连斯基，带着欧洲的"七大姑八大姨"飘洋过海来到白宫——这个昔日 让他们向往、今日令他们生畏的地方。 一、欧乌的"四大转变"和"三道防线" 回顾欧乌方面应对俄乌冲突的基调和策略，我们可以发现"四大转变"和"三道防线"。 所谓"四大转变"是指三年半以来欧乌对胜败把握的口径和基调的变化，主要表现在以下不同的阶段： 2022年2月24日遭到俄军攻击后，欧洲随处可闻"乌克兰必败论"； 乌克兰的顽强抵抗及时制止了悲观情绪的蔓延，欧洲 ...
