You really made sense dear
I believe the moment US or any other country officially send in their troops to either support Russia or Ukraine then that would be the spark of WW3.
but currently there is a humanitarian corridor given in favour of Ukraine and this is just a grammatical expression as we all know that this simply means a means of assistance to Ukraine which the US and so many other countries has offered well I hope all these will soon end as my heart beat for Ukraine as same was experienced in Nigeria in 1967 through 1970 where millions of our people where annihilated till all that was intended for the war was actualized. Nice suggestion from your end ✋
