The Iskander-M, capable of carrying both conventional and nuclear warheads, poses a direct threat to U.S. allies in Eastern Europe, and will be arriving at a time when Russia’s deployed nuclear arsenal has now outstripped America’s by 429 warheads. As The Daily Beast reported, this exceeds the cap on warheads, set to be fully in place by 2018, as agreed to in the New Strategic Arms Reduction Treaty, although the numbers could well vary until then. (The Iskander intelligence coincided with the alleged violation of Estonian and Finnish airspace by Russian Su-27 jet fighters.)

But Russia hasn’t only been amassing a new arsenal in Europe.

In the fortnight following a collapsed U.S. and Russian brokered “ceasefire” for Syria, Putin has doubled supply runs by air and sea of materiel intended to bolster the Assad regime, according to Reuters. In all likelihood, the supplied are intended to help it and its Iranian proxies retake rebel-held eastern Aleppo.

The cargo has included the revamped S-300VM antiaircraft missile system, which can (theoretically) take out U.S. warplanes should any come within range. The Kremlin’s chief media mouthpiece, the U.S.-sanctioned Dmitry Kiselyov, who hosts the tabloid propaganda show News of the Week, was straightforward: “We’ll shoot them down.”
