The overall amount of the nuclear ammunition across the globe has dropped since the beginning of 2018 - but the governments of these countries boost funding for the development and modernization of the nuclear arsenal; this is mentioned in the latest report by SIPRI.
As of early 2018, the nine nuclear states have wielded totally 14,465 warheads - that's 470 less than the previous year; 3,750 of those are combat-ready the survey says.
'The decrease in the overall number of nuclear weapons in the world is due mainly to Russia and the USA—which together still account for nearly 92 per cent of all nuclear weapons—further reducing their strategic nuclear forces pursuant to the implementation of the 2010 Treaty on Measures for the Further Reduction and Limitation of Strategic Offensive Arms (New START)', reads the report.
The U.S. is also claimed to assign about USD 500 billion for modernization program.
'The nuclear arsenals of the other nuclear-armed states are considerably smaller, but all are either developing or deploying new nuclear weapon systems or have announced their intention to do so. India and Pakistan are both expanding their nuclear weapon stockpiles as well as developing new land-, sea- and air-based missile delivery systems. China continues to modernize its nuclear weapon delivery systems and is slowly increasing the size of its nuclear arsenal', the survey says.
