根据丹麦情报部门的一份报告，俄罗斯入侵乌克兰已超过四年，目前正承担更多风险并遭受“惨重损失以换取微小的领土收益”，同时加剧了对西方的破坏活动和网络攻击。为何重要：这对莫斯科来说前景黯淡，对欧洲而言则是红色警报。
More than four years into its invasion of Ukraine, Russia is taking more risks and suffering "heavy losses for marginal territorial gains" — while intensifying its use of sabotage and cyberattacks against the West, according to a Danish intelligence report. Why it matters: It's both a bleak outlook for Moscow and a red alert for Europe.
新闻背景：丹麦国防情报局（DDIS）于9月24日分享了其对“俄罗斯威胁”的评估，其中包括近期无人机和导弹侵入北约领空以及波罗的海发生的护卫舰与直升机对峙事件。这份三页的文件是对去年初发布的一份报告的补充。
Driving the news: The Danish Defense Intelligence Service (DDIS) on Sept. 24 shared its assessment of the "Russian threat," accounting for recent drone-and-missile incursions into NATO airspace and a frigate-and-helicopter dustup in the Baltic Sea. The three-page document supplements a report published early last year.
深层含义：俄罗斯的好战行为受到乌克兰总统弗拉基米尔·泽连斯基所称的“远程制裁”或对关键基础设施成功进行深度打击的影响。
Between the lines: Russian belligerence is being influenced by what Ukrainian President Volodymyr Zelensky calls "long-range sanctions," or successful deep strikes on critical infrastructure.
宏观视角：丹麦报告指出，受国防支出和国际制裁的影响，俄罗斯经济正处于“重大危机”的边缘。
Zoom out: The Russian economy is on the brink of "a major crisis," the Danish report notes, spurred in part by defense spending and international sanctions.
自战争开始以来，俄罗斯军队伤亡人数已超过100万。据认为，今年夏天伤亡人数已超过了征兵速度。
The Russian military has suffered more than 1 million casualties since the war began. This summer, casualties were thought to be outpacing recruitment.
接下来会发生什么：预计俄罗斯总统弗拉基米尔·普京将继续抨击乌克兰的邻国和支持者，但丹麦国防情报局表示“没有迹象”表明俄罗斯即将入侵北约国家。
What's next: Russian President Vladimir Putin is expected to continue lashing out at Ukraine's neighbors and supporters, but the DDIS saw "no indications" of a looming invasion of a NATO country.
