Fearing a continuity of Soviet-era policies, Iran supported the Islamic and nationalist opposition during the civil war.
At the end of 1992, Tajikistan entered into a bloody civil war. Tehran gave refuge and support to the leaders of the Democratic-Islamic coalition of the Tajik opposition, and was therefore considered to be a pro-Islamic actor. However, it also contributed a critical role in helping peace discussions: Tehran hosted several rounds of the Tajik peace negotiations in 1994, 1995, and 1997, bringing both sides to the discussion table. President Rahmon paid an official visit to Tehran in 1995 and opened an embassy there. But seen from Dushanbe, Moscow was a more reliable ally than Tehran, and any kind of pan-Persian nationalism was rapidly shut down by the authorities.
Tajikistan has accused Iran of having played a subversive role in the country's civil war in the 1990s by sending terrorists to the Central Asian republic, the latest sign of deteriorating relations between the two countries.

Armenia has said that Turkey was directly involved in the fighting in and around Nagorno-Karabakh, and that a Turkish F-16 fighter shot down an Armenian jet. Turkey denied those accusations.
Turkey's support for Azerbaijan has been vital, and Azerbaijan's superior weaponry and battlefield advances have reduced its incentive to reach a lasting peace deal. Ankara denies its troops are involved in fighting but Aliyev has acknowledged some Turkish F-16 fighter jets remained in Azerbaijan after a military drill this summer, and there are reports of Russian and Turkish drones being used by both sides.
Although Azerbaijan and its ally Turkey deny the use of mercenaries, researchers have amassed a considerable amount of photographic evidence, drawn from videos and photographs the fighters have posted online, which tells a different story.
According to sources within the Syrian National Army (SNA), the umbrella term for a group of opposition militias backed by Turkey, around 1,500 Syrians have so far been deployed to the disputed Nagorno-Karabakh region in the southern Caucasus ... Shortly after conflict erupted between Armenia and Azerbaijan, Turkey sought to mobilize the SNA, sometimes called Turkey's proxy army ... The first fighters were transferred in late September to southern Turkey and then flown from Gaziantep to Ankara, before being transferred to Azerbaijan on Sept. 25.
This response was too much for the commander of the 14th Army General Yuri Netkachev, who ordered Russian troops to drive out the Moldovan forces. The 14th Army had always supported the separatists since the very beginning, but this direct support was the first open participation in combat. ... The participation of the 14th Army was indispensable for the victory of the separatists, ... Moldovan forces were concentrated in a forest near Bender, and Lebed decided to stop their advance by relying on his powerful artillery. At 0300 on 3 July massive barrages rained down on the unsuspecting Moldovans ...
Neither side had a proper military force. The intervention of the Russian Fourteenth Army and its commander General Alexander Lebed on behalf of the Transdniestrians was decisive.
Hence their wholehearted support for Yeltsin in his September–October 1993 confrontation with the Left-nationalist radical supporters of the Supreme Soviet. The Czech President Václav Havel said October 4 that the clashes in Moscow were not simply 'a power struggle, but rather a fight between democracy and totalitarianism.' In a joint statement Presidents Lennart Meri of Estonia, Guntis Ulmanis of Latvia, and Algirdas Brazauskas of Lithuania called the struggle in Moscow 'a contest between a democratically elected President and antidemocratic power structures.' Their Moldovan counterpart, Mircea Snegur, called the Supreme Soviet supporters 'Communist, imperialist forces who want to turn Russia into a concentration camp'. 'In my thoughts I am on the barricades with the defenders of Russian democracy, as I was next to them in August 1991,' Eduard Shevardnadze said in a message to the Kremlin on the late afternoon of October 3, 1993, when the outcome looked quite grim for Yeltsin. 'Deeply concerned about the events in Moscow, I am again expressing my resolute support for President Yeltsin and his allies.'
Unlike Chisinau, the leaders of the Transnistrian separatists supported almost openly the Rutskoy-Khasbulatov camp, sending paramilitaries from Transnistria to the Russian capital to defend the White House. On October 4, the Moldovan ambassador in Moscow gave an interview for the Russian press, in which he warned about the presence of representatives of paramilitary detachments of the Transnistrian separatists among the defenders of the White House.
The Ukrainian Government maintains that the Russian Federation has from 27 February 2014 exercised effective control over the Autonomous Republic of Crimea and the city of Sevastopol ... There was sufficient evidence that during the relevant period the respondent State [Russia] had exercised effective control over Crimea.
Russia's war against Ukraine began with the annexation of Crimea on 27 February 2014. On that day, Russian special forces without any uniform insignia appeared in Crimea, quickly taking control of strategic, military and political institutions.
During the night of 26–27 February, Russian special forces without insignia departed Sevastopol ... They arrived at the Crimean Rada and Council of Ministers buildings in Simferopol, disarmed the security and took control of the buildings ... Putin later signed a decree designating 27 February as Special Operations Forces Day in Russia.
Mr. Prystaiko (Ukraine): I have to remind the Council that the official medal that was produced by the Russian Federation for the so-called return of Crimea has the dates on it, starting with 20 February, which is the day before that agreement was brought to the attention of the Security Council by the representative of the Russian Federation. Therefore, the Russian Federation started – not just planned, but started – the annexation of Crimea the day before we reached the first agreement and while President Yanukovych was still in power.
I will be frank; we used our Armed Forces to block Ukrainian units stationed in Crimea
Before dawn on Feb. 27, at least two dozen heavily armed men stormed the Crimean parliament building and the nearby headquarters of the regional government, bringing with them a cache of assault rifles and rocket propelled grenades. A few hours later, Aksyonov walked into the parliament and, after a brief round of talks with the gunmen, began to gather a quorum of the chamber's lawmakers.
