U.S. Navy launches Hormuz blockade as Iran imposes tolls and mines
President Trump ordered a U.S. Navy blockade of the Strait of Hormuz effective April 13, targeting any vessel entering or leaving Iranian ports. Iran responded with a de‑facto toll‑booth regime charging up to $2 million per ship and laying partially undetected mines, heightening oil‑market volatility with Brent crude above $120 a barrel.

The Price of European Military Space Autonomy
European nations are committing roughly $109 billion to military space programs by 2030, but the IISS warns that this level of funding falls short of true autonomy from U.S. capabilities. An extra $10 billion would close the most critical gaps for limited burden‑sharing, while full independence would demand at least another $15 billion plus heavy‑launch and counter‑space assets. The report stresses that fragmented national spending and weak coordination hinder progress, and that achieving genuine autonomy will require deeper political integration and industrial pooling beyond the 2030s.
