**What’s at Stake?**
The Ukraine crisis is a major threat to European security. A Russian victory would embolden Putin and could lead to further aggression against other countries in the region. It would also undermine the post-Cold War order that has been in place for the past three decades.
The United States and its allies have imposed sanctions on Russia in an effort to deter further aggression. However, it is unclear whether these sanctions will be enough to stop Putin.
The Ukraine crisis is a complex and rapidly evolving situation. It is important to stay informed about the latest developments and to understand the stakes involved.
