NATO leaders to approve "significant troop enhancements" in response to Putin's conflict in Ukraine.

• The alliance is likely to increase its military presence on its eastern border, according to NATO Secretary-General Jens Stoltenberg, who made the statement on Wednesday.
• In response to the Kremlin's invasion of Ukraine in February, NATO has positioned 140,000 troops and amassed a significant amount of advanced military equipment in the region.
• Stoltenberg and Biden cautioned that Putin may employ chemical weapons in Ukraine, altering the conflict's course.

The alliance is likely to increase its military presence on its eastern border by deploying four new battle groups in Bulgaria, Hungary, Romania, and Slovakia, as stated by NATO Secretary-General Jens Stoltenberg on Wednesday.

Stoltenberg stated during a press conference prior to the NATO leaders summit in Brussels that he anticipates leaders will enhance NATO's posture across all domains, with significant increases occurring in the eastern part of the alliance on land, in the air, and at sea.

The United States has contributed 100,000 soldiers out of the 140,000 troops NATO has mobilized in the region since the Kremlin's invasion of Ukraine in February.

Currently, U.S. service members and NATO troops are positioned in neighboring NATO countries and are not directly engaged in combat with Russian forces within Ukraine.

On Wednesday, U.S. Ambassador to NATO Julianne Smith stated that the possibility of permanently stationing U.S. and NATO troops is being considered.

Smith stated that NATO is currently reassessing its medium and long-term force presence in its eastern flank territory, with the new deployments conveying a clear message to Moscow.

Smith stated that permanent stationing or persistent rotations could be potential solutions. At this juncture, the military commanders must provide specific proposals to the alliance, and then we must assess the security environment's requirements.

The alliance, with over 140 warships and 130 aircraft on high alert, has previously warned Putin that an attack on a NATO member state would be considered an attack on all, invoking the group's Article 5, which calls for a military response from member nations.

Since 2002, Ukraine has sought NATO membership and is surrounded by four NATO allies: Poland, Slovakia, Hungary, and Romania. Currently, Poland hosts the most NATO troops and has taken in the majority of refugees escaping Putin's war.

On Wednesday, President Joe Biden stated that the use of chemical weapons by Putin to attack Ukraine is a real threat, as he is expected to travel to Poland after the NATO leader's summit on Thursday.

This month, Biden cautioned Putin might employ "false flags" to justify a chemical or biological attack on Ukraine.

Biden stated at a Washington business event on March 21 that the individual is now discussing false flags being set up and asserting that America has biological and chemical weapons in Europe, which is not true, he guaranteed.

Biden stated that the suggestion that Ukraine possesses biological and chemical weapons is a clear indication that he is considering using them, despite not providing any evidence.

At the alliance headquarters in Brussels, Stoltenberg informed reporters that the use of chemical weapons would alter the course of the conflict in Ukraine.

Stoltenberg stated that the use of such weapons would be a clear violation of international law and could have severe consequences, affecting not only the country in question but also NATO member nations nearby.

Stoltenberg stated that the NATO alliance will soon give Ukraine weapons to defend against chemical, biological, radiological, and nuclear threats. However, he did not disclose the specific type of support the alliance would offer due to operational security concerns.

Previously, Russia employed chemical weapons in various conflicts, such as in Syria, against Kremlin critic Alexei Navalny, and against former Russian spy Sergei Skripal and his daughter Yulia in London.
