Ukraine and U.S. Sign Deal on Proceeds From Rare Earth Minerals

The deal is intended to give the U.S. access to proceeds from Ukraine’s reserves of rare earth minerals.

The agreement concludes months of fraught negotiations over whether the United States will continue to provide Ukraine with economic and military support for Ukraine as it tries to broker an end to its war with Russia. The economic agreement is intended to provide Ukraine with an implicit security arrangement while addressing President Trump’s concerns that the U.S. has provided Kyiv with a blank check.

The hell is an implicit security arrangement??
