Why the U.S. can never deploy forces on Iranian soil? / In such a campaign, willpower speaks first. The newspaper Jomhuri-ye Eslami wrote: 🔹️ Southern Iran has a history of brave resistance against numerous foreign invasions, from the British to the Portuguese, and history has shown that in none of these cases have the people of this region been willing to accept foreign domination, and all invasions have ended in failure. 🔹️ American soldiers are filled with fear and are anxiously looking for an escape from mandatory missions and a way to flee from confronting the Iranian people and fighters.
