The first half of the year on the world financial markets broke the expectations of the overwhelming majority of its participants. The bets on the strengthening of the dollar and "American exceptionalism", which provided a large-scale inflow of money into US assets, did not work. Donald Trump has turned from a politician, who was expected to support business and the economy, into a figure who unleashed a trade war and questioned the hegemony of the dollar. The European stock market <a href="https://oninvest.com/article/iz-maga-v-mega-kak-tramp-delaet-evropu-snova-velikoj">played</a> the role of Cinderella: the battered, unloved stepdaughter turned out to be a beautiful princess.

In June of this year, Iran's nuclear program suddenly turned from a subject of diplomatic disputes and economic sanctions into a target of missile strikes. On June 13, Israel attacked key Iranian nuclear facilities, and on the night of June 22, the United States joined the operation. The airstrikes were the first time Iran's nuclear infrastructure has been hit. Maxim Starchak, a researcher at the Center for International and Defense Policy at Queens University, examined whether the Islamic Republic's nuclear program has been eliminated.

In the line of fire: what's left of Iran's nuclear program

"The atomic bomb hanging beneath the fuselage of the plane...came off the fighter-bomber that was disintegrating in mid-air and continued its flight eastward. It fell far from the place where the burning remains of the plane had crashed, fifty meters from the house of the Druze farmer... And now the Israelis were faced with a problem that was impossible to solve, even for those of them with a rich imagination. The bomb was somewhere in Syrian territory - but where exactly? Which of the four airplanes was carrying it? Where did it crash? The Israelis could not ask the Syrians to search for it. And what to say to the Americans, from whom they managed with considerable dexterity to acquire "special nuclear material", a fact that both sides categorically denied? Thus, the atomic bomb lay buried two meters into the ground near the house of a farmer who, unaware of its existence, continued to cultivate his field, which was strewn with stones here and there.
