Currently, tension has reached its peak in the diplomatic corridors of the Middle East and around the world, and the biggest reason for this is the increasing war of words between Iran and the United States. On one hand, the tussle between global superpowers regarding nuclear weapons and security continues, while on the other hand, Tehran's attitude has become even more aggressive. An open warning has once again been issued to America by the top leadership and military officials of the Iranian government. Iran has bluntly said that if America or any of its allies dares to carry out any nuclear or military attack on its soil, it will be given a very befitting and devastating response. Amidst this sharp rhetoric, the eyes of Iranian strategists are now focused on the moves of European countries and their reactions, which has brought a new earthquake in international politics. Why is tension increasing between Tehran and Washington? During the last few months, relations between America and Iran have reached the stage of turning into a major military conflict at any time. The US and Western countries are continuously putting pressure on Tehran regarding Iran's nuclear programs, its increasing level of uranium enrichment and the activities of its proxy groups in the Middle East. Countries like the US and Israel can never tolerate Iran reaching the threshold of nuclear weapons, while Iran has always argued that its entire nuclear program is entirely for peaceful purposes and energy needs. Due to this fundamental ideological and strategic difference, diplomatic dialogue between the two countries has almost come to a standstill and continuous threats from both sides continue on the military front. Iran's military warning and country's defense preparedness: Iran's senior military commanders and government spokespersons have recently made it clear in an official statement that their army is fully prepared to deal with any situation. He said that the Iranian armed forces have the full capability to defend its sovereignty and the geographical integrity of the country. Tehran has warned that if the Washington government takes any audacious step, US military bases and their interests in the Middle East will be destroyed. The aim of this aggressive strategy of Iran is to prevent America and its allies from taking any kind of military action, so that they are forced to talk on their own terms instead of bowing to diplomatic pressure. The suspicious role of European countries and the keen eye of Tehran Amidst this entire geopolitical conflict, a major focus of Iran's diplomacy is on the stance of Europe and the European Union (EU). Tehran is well aware that European countries can play an important mediating role in avoiding or controlling a direct conflict with the US. However, major European countries like Britain, France and Germany have so far been seen standing in support of American policies and have been advocating maintaining economic sanctions on Iran. Despite this, Iran is continuously trying to keep its diplomatic channels open with European capitals so that if any serious crisis arises with Washington, some diplomatic space can be created through the European countries. This keen eye of Tehran is an indication that it is not only relying on military power but is also making full moves on the diplomatic front. Looming threats to global peace and the way forward The ongoing cold war between Iran and America and such nuclear threats have become a matter of deep concern for the entire world. If any kind of direct military conflict breaks out between these two countries, its consequences could prove disastrous not only for the Middle East but also for the entire global economy. Everything from crude oil supply to international maritime trade could be in serious trouble. Peace-loving countries around the world and the United Nations (UN) are constantly appealing to both sides to exercise restraint, but the kind of aggressive rhetoric and military preparations going on on the ground make it clear that the coming days are going to be very turbulent and sensitive in terms of global diplomacy.
