The United States reached its long-anticipated decision on sanctions over Turkey’s purchase of the S-400 air defense system from Russia. Outgoing U.S. President Donald Trump imposed Countering America's Adversaries Through Sanctions Act (CAATSA) sanctions on NATO ally Turkey's Presidency of Defense Industries (SSB) under pressure from U.S. Congress. The sanctions, as they stand, are not necessarily severe, although there is the possibility of additional steps being taken. However, what is important is that there is now room for the incoming U.S. administration to reengage with Turkey.

As predicted, the administration of Donald Trump has announced sanctions against Turkey because of its procurement of Russian S-400 air defense missile systems. Sanctions were imposed against Turkey’s Presidency of Defense Industries (SSB) and four individuals, including SSB head Ismail Demir.

At the beginning of the week, the U.S. Treasury Department imposed sanctions on Turkey over its purchase of Russian S-400 missile defense systems.

Various geopolitical issues, in which Turkey has taken active steps in recent years, are quickly developing and on two key fronts, the conflict has given way to reconciliation.

Democratic presidential nominee Joe Biden’s plan to remove Turkish President Recep Tayyip Erdoğan from power went down in the history of Turkish-U.S. relations. The fact that he made that statement some eight months ago does not make the situation any less grave. After all, those controversial words were not uttered by an inexperienced presidential candidate with no idea about foreign policy. Biden, who was President Barack Obama’s vice president, unveiled a thought-out and clear policy on Turkey.

The effective steps Turkey has taken to fill the deepening power vacuum in its region have hurt the interests of many foreign governments. Those countries are unsettled by Turkey’s transformation into a regional and global player with game-changing capabilities under President Recep Tayyip Erdoğan’s leadership.

Wednesday will be the fourth anniversary of the July 15 coup attempt in Turkey. Four years ago, Turkish people defeated an attempt to overthrow the country's democratically elected government. The people demonstrated their commitment to democracy by organizing mass rallies for more than 30 days after July 15, to prevent another such attempt.

French President Emmanuel Macron once said the 'NATO is brain dead.' Considering all the confusion the alliance is facing at critical moments, this statement has some basis. Lack of trust among the member countries and lack of cooperation and coordination have become some pervasive features of the strongest military alliance in modern history.

Ankara’s intervention in Libya fueled a fresh debate in European and Middle Eastern capitals on Turkey's role in the world. Reflecting the view that Turkey has evolved into a more powerful player, that discussion has two dimensions: First, it concentrates on the concrete shifts in the balance of power in Syria, Libya and the Eastern Mediterranean. At the same time, it is a propaganda war with lots of speculation about "real" intentions. It would be impossible to make sense of Turkey’s most recent moves, capabilities and objectives without distinguishing those two aspects.

Tensions have once again peaked between Turkey and Greece over a number of traditional disputes involving the Aegean and Cyprus, as well as over recent disagreements regarding maritime jurisdiction in the Eastern Mediterranean. Athens has attempted to invalidate Turkey’s November 2019 agreement with Libya to limit Turkish control over area in the Eastern Mediterranean spanning to the Gulf of Antalya. Athens believes it can pursue an unjust and maximalist policy with support from France, Egypt, the United Arab Emirates (UAE) and Greek Cypriots. Given the recent dispute over the Aegean continental shelf, the Eastern Mediterranean has emerged as the main platform for a renewed rivalry between Turkey and Greece.

Neo-isolationism is among the expectations for U.S. rhetoric in the aftermath of the coronavirus pandemic and this can melt its frozen ties with Turkey

The March 5 agreement between Turkey and Russia put an end to the military confrontation in Idlib, Syria. President Recep Tayyip Erdoğan and his Russian counterpart, Vladimir Putin, shook hands on that deal to de-escalate what had become serious bilateral tensions. The 2018 Sochi agreement has thus been updated.

After a six-hour meeting between leaders and technical committees, President Recep Tayyip Erdoğan and his Russian counterpart announced a cease-fire for Syria's Idlib. During the meeting at the Kremlin, the presidents gave short speeches. The whole world followed the process as the decisions could trigger an escalation in violence while intensifying the humanitarian crisis unfolding in Syria. Turkey and Russia both wanted to end the civil war but were unwilling to concede their positions. For both Turkey and Russia, bilateral relations were at stake as well.

Turkey's objectives amid the recent tensions in Idlib are clear and the scope of a possible military operation would be limited..

It is true President Recep Tayyip Erdoğan and Russian President Vladimir Putin have had an amenable relationship. Turkey and Russia are also both regional actors that share partnerships on many issues. The recent cooperation between the two countries is not as black and white as foreign affairs and alliances between countries were during the Cold War. To call this period of cooperation a "honeymoon," however, would be incorrect.

The Syrian civil war has always had great potential to worsen any day. Since May 2019, the Bashar Assad regime has been pummeling the Syrian opposition's last holdout in the northwestern province of Idlib.

The U.S. Senate passed a resolution on Thursday recognizing the so-called Armenian genocide. The measure, which President Donald Trump's allies in the Senate had repeatedly blocked, is not legally binding. It is merely a symbolic step. For the resolution, which Turkey strongly condemned, to become law, it must be adopted by the House of Representatives and signed by President Trump.
