FranceFrench President Macron's call for incorporating France's nuclear arsenal into broader European defense sparks fierce debate, with critics from both left and right expressing concerns over national sovereignty and strategic autonomy.France's nuclear weapons should be part of the European defence debate, French President Emmanuel Macron told a group of regional newspapers on Sunday, in comments that drew fire from his political opponents ahead of EU elections in June.Macron has been more strident on defence issues recently, having called on Thursday for stronger, more integrated European defences as he outlined his vision for a more assertive European Union on the global stage, saying "Europe could die".In an interview set up by EBRA, a group of French eastern regional newspapers, he said a "credible European defence" should go beyond the protection already offered by NATO."That may mean deploying anti-missile shields, but we need to be sure that they block all missiles and deter the use of nuclear weapons," he said.Regarding nuclear weapons, while France's doctrine has so far been to use them when the country's vital interests are threatened, Macron said he was open to give a more "European dimension" to these interests."I'm in favour of opening this debate, which must therefore include missile defence, long-range weapons and nuclear weapons for those who have them or who have American nuclear weapons on their soil," he said.His comments drew criticism from opponents on the right and the left of the political spectrum on Sunday."Macron is becoming a national danger!," far-right European lawmaker Thierry Mariani wrote on social media platform X."#We can't wait for June 9th to give him a clear signal that his policies are over!," Mariani, a member of France's Rassemblement National (RN) headed by Marine Le Pen, added in a reference to the approaching EU parliamentary elections."These comments are exceptionally serious," said European lawmaker Francois-Xavier Bellamy, who will lead right-wing party LR into the EU vote."We are touching the nerve of French sovereignty", he added in an interview on Europe 1 radio station.Those at the other end of the political spectrum were equally angry at Macron's comments."The nuclear deterrent cannot be shared," said far-left French lawmaker Bastien Lachaud on X. "Under the guise of defending European soil, #Macron wants to liquidate France's strategic autonomy."

World Stealth aircraft, designed to minimize their radar signature, pose a significant challenge for traditional air defense systems. But what about Earth horizon radars? Can they pierce the veil of invisibility surrounding these advanced jets?The truth is, there's no single "Earth horizon radar" specifically designed for stealth detection. However, there are radar technologies that can be effective in this role, and understanding the Earth's curvature plays a part.Traditional Radar vs. StealthTraditional radars work by emitting radio waves and analyzing the reflections that bounce back from objects. Stealth aircraft, however, are designed to absorb or deflect these waves, significantly reducing their radar cross-section (RCS) – essentially making them appear much smaller on radar.Earth Horizon and Detection ChallengesThe Earth's curvature creates a limitation for traditional line-of-sight radars. There's a point beyond which the radar beam dips below the horizon, creating a blind spot for low-flying targets. This is the radar horizon.Here's where things get interesting:Over-the-Horizon Radars (OTH): These systems exploit the ionosphere, a layer of the atmosphere that can refract radio waves. By bouncing signals off the ionosphere, OTH radars can "see" beyond the horizon, potentially detecting targets at much greater distances, including those that might be trying to remain hidden by hugging the Earth's surface.Beyond the Horizon: Other Stealth CountersOTH radars are just one approach. Here are other methods that can complement them:Low-Frequency Radars: While stealth aircraft are optimized to deflect higher-frequency radar waves, low-frequency radars can be less susceptible to these techniques. Their longer wavelengths can interact with the aircraft's structure in ways that provide a signature.Multistatic Radars: These systems use multiple radar stations spread out geographically. By analyzing the signals from different locations, they can build a more complete picture of a target's position and characteristics, potentially revealing a stealth aircraft even if its RCS is low from a single direction.The Evolving Chess GameIt's important to remember that stealth technology and radar detection methods are constantly evolving. As radar systems improve their ability to exploit weaknesses in stealth design, aircraft developers will undoubtedly refine their techniques to minimize their signatures.The Earth horizon might not be a singular solution, but it plays a role in the broader strategy of air defense. By combining various radar technologies and exploiting the properties of the Earth's atmosphere, militaries can enhance their ability to detect even the most elusive aircraft.
