Traditionally, Türkiye-Iran relations have been defined by a mix of competition and cooperation. Sharing a long land border and possessing a multidimensional historical depth, numerous dynamics simultaneously affect the relationship between the two countries.

The recent developments in the Middle East region have led to a deepening instability, with the possibility of conflict increasing day by day. In 2023, we witnessed a period of relative normalization in the Middle East. While countries in the region were trying to minimize the potential for conflict, they had come a long way in developing common potential.

Parliament returned from recess on Tuesday to debate the PKK’s terror attacks. The PKK carried out suicide attacks against the Turkish forces in northern Iraq on Dec. 22 and Jan. 12, claiming 21 lives. That development fueled a multifaceted debate in Türkiye.

On Jan. 4, Tehran Times, an international newspaper of Iran, described Qassem Soleimani, who was killed by the United States in Iraq, as the “architect” of the new regional geometry in the Middle East. On the same day, a terrorist attack occurred in Kerman, Iran, killing more than 100 civilians.

The year 2023 began relatively strong for the U.S. in terms of its claim to global leadership in foreign policy. However, due to a strategic blind spot in the context of the Gaza conflict, it ended on a disappointing note. In the upcoming year, it is not difficult to predict that the Biden administration will attempt to diminish this loss of reputation. However, President Biden's unwavering support for Israel poses a significant obstacle. While Washington acknowledges the unsustainability of this stance, overcoming it to influence Israel's "war cabinet" will require more than leaking discontent to the press. In 2024, Biden must shift his focus from providing ideological support to Israel and concentrate on repairing America's political interests and reputation. Failing to do so will hinder his ability to unite his party or establish superiority in the power struggle with Russia and China.

In this new volume of SETA Security Radar, we analyze the main dynamics shaping Türkiye’s security and geopolitical landscape with references to the most significant foreign policy and security issues throughout 2023.

The events of 2023 have significantly diversified potential geopolitical and strategic scenarios for 2024.

Even if Israel emerges from the Israeli-Palestinian conflict with a limited military victory, it remains the loser of the conflict. Following its intense campaign against Gaza post-Oct. 7, Israel either failed or chose not to seize the greatest historical opportunity since its establishment. Today, it grapples with an ontological security crisis and profound regional and global status anxieties on a scale unseen since 1948.

The prisoner exchange agreement reached between Israel and Hamas marks a significant turning point in the course of the war. The agreement implies that Israel has stepped back from its pledge to halt operations until all prisoners are released. However, it is clear that Israeli attacks will continue after a brief hiatus. Predicting that the release of all Hamas prisoners will take months, if not years, it is not difficult to anticipate that the conflict will intermittently intensify and persist for an extended period. The events since October 7 have become the foremost agenda item in the region, transforming the pursuit of a solution to the Palestinian issue into a new driving force. Therefore, in the coming period, we can expect the Gaza war to continue with its ups and downs, while diplomatic efforts for a final resolution intensify.

The operation launched by Hamas against Israel on Oct. 7 continues, accompanied by Israel’s extensive air and ground operations. Israel’s military attacks carried out to overcome the shock experienced within the country, reestablish military deterrence and eliminate Hamas through the collective punishment method have now completed their 24th day.

The ongoing Israeli offensive in Gaza, resulting in the tragic loss of more than 7,000 lives, has the potential to mark a significant turning point in Middle East geopolitics. Israel’s contemplated ground offensive introduces a range of dynamics that suggest the conflict between Israel and Hamas will extend beyond Gaza. Historically, these conflicts followed a familiar pattern: Hamas attacks against Israel, Israeli airstrikes on Gaza, a cease-fire, and a return to the status quo. However, the events of Oct. 7 strongly indicate a departure from this pattern, with Israel possibly establishing a lasting presence in at least the northern sector of Gaza, thereby altering the status quo.

The Israeli-Palestinian conflict threatens to spread across the region and exacerbate great power competition. As United States military bases in Iraq and Syria come under drone attacks more and more frequently, a U.S. destroyer in the Red Sea shot down cruise missiles that the Houthi rebels in Yemen fired at Israel – harassing fire from Iran’s proxies.

Hamas’ surprising attack on Israel on Oct. 7, followed by Israel’s ongoing and disproportionate military operation in Gaza, has the potential to become a pivotal moment in Middle Eastern history. Predicting the extent of Israel’s incursion into Gaza remains uncertain, and Hamas faces immense challenges in maintaining its resistance.

Hamas initiated a large incursion into some Israeli cities last weekend, which has led to a new cycle of violence in Palestine. So far, around 900 Israelis have been killed and more than 2,600 people wounded. In addition, Hamas has taken more than 100 people, including many soldiers, as hostages. On the Palestinian side, about 700 people were killed by the Israeli security forces, and several thousands of people were wounded.

The Qassam Brigades launched a comprehensive attack on Saturday, causing the Israel-Palestine conflict to recapture the world’s attention anew after long years. Initially shocked by the assault, Israel has been bombarding the Gaza Strip. Israeli Prime Minister Benjamin Netanyahu stated that “our response to the Gaza attacks will change the Middle East” as his government’s defense minister, Yoav Gallant, described the scope of the Israeli counterattack as follows: “Everything will be cut off – no electricity, no water, no food, no fuel. We are fighting human-like animals, and we will act accordingly.”

Türkiye carried out airstrikes in Syria and Iraq last week in response to a terrorist attack against the Interior Ministry in Ankara. During that period, one statement and one picture attracted plenty of attention.

The political dynamics within the American Congress and the activities of lobbying groups have long been significant factors negatively impacting Turkish-American relations. Since the 1970s, Congress has constrained the broad authority of the White House in foreign policy, leading to decisions against Türkiye on issues such as Cyprus and Armenia. In recent years, Congress has extended its influence into areas like Syria and defense cooperation.
