After four years of war in Ukraine, peace remains elusive

Russia's full-scale invasion of Ukraine has passed four years and fighting continues along a long, active front; U.S.-mediated talks have so far failed to produce an agreement and U.S. officials have cited a June deadline for a settlement.

Russia's full-scale invasion of Ukraine has passed four years and the front line remains active with only limited territorial change. International mediation led by the United States has continued but has not produced a peace agreement. Senior leaders hold opposing demands that have so far prevented a deal. Officials and think tanks report heavy military and economic costs on both sides. Key reported facts: - The conflict surpassed roughly 1,418 days, and Russia controls territory captured since 2014, amounting to about one-fifth of Ukraine's land according to reports. - Fighting continues along a long front line with slow advances reported and limited new territorial gains in recent years. - Analysts and research centers have published wide-ranging estimates of military casualties and economic strain for both countries. - U.S.-mediated talks remain ongoing and U.S. officials have referenced a June deadline for a possible settlement. Summary: Diplomatic talks have continued amid ongoing combat and entrenched positions from both Moscow and Kyiv, and a quick settlement appears unlikely given current demands. The next notable timeline mentioned by U.S. officials is a June deadline for progress toward an agreement, while the broader outcome remains undetermined at this time.
